Chapter 425: Forensic Science

The key to not wanting to cause too much trouble in the court is whether we can collect enough evidence to force the other party to retreat. According to Tan Xiaopei, the best strategy is to provide enough evidence and then show up with the Wang family and the people inside and outside the court, so that the other party can't argue, calmly withdraw from all conspiracy and outsourcing, and calm the matter down. In this way, everyone's face is better, and at least on the surface, Dongping still maintains the tradition of no party fighting for the throne, at least, can also make

Tan Weiming's family will not be affected too much. If this is not possible, Tan Xiaopei and Nie Rui also have a backup plan, so they are ready to use a series of measures to lure and guide each other to take some extreme actions. As long as such actions are formed, with the current Intelligence Bureau, the Imperial Guard, Tan Weiming, and Tan Weiran brothers, they can naturally control the matter in a short time and collect enough evidence of crime for further disposal. However, in this way, the impact of the Bureau will be greater.

The fact that collecting evidence is really not what the Intelligence Bureau is good at. Nie Rui's Intelligence Bureau has indeed had a technical department due to the suggestions of Tan Weixin and Ye Tao. This technical department has provided various very convenient tools for the cutting-edge intelligence personnel over the years, packaging many useful weapons, tools, drugs, poisons, etc., so that intelligence personnel can bring what they want to carry anywhere and carry out various tasks. These people from the Intelligence Bureau's technical department,

The most specialized are poisons and assassination tools. In terms of outdoor equipment, scout equipment, and observation equipment, the technical department has always relied on the Ye Workshop. Since the Ye Workshop has been studying various scout equipment, it can be equipped with intelligence personnel with a slight improvement. In terms of forensic science, the technical department is very weak. If you have any more to do, it is the technical department's research on handwriting, paper and ink. In the materials room of the technical department, almost all kinds of paper and ink are collected in the world.

There are many masters who are proficient in this study and study the various characteristics of paper and ink. In terms of handwriting comparison, the technical department relies on its strong connections and has many Dongping calligraphy people willing to cooperate with them. They are often secretly invited to a room of the Intelligence Bureau to assist in the comparison. Under the influence of these calligraphy masters and under the more professional training of the Intelligence Bureau, the Intelligence Bureau's own writing experts are about to take shape. These people are even more terrifying than those calligraphy masters, and the calligraphy master can only use the characteristics of the handwriting.

It is inferred whether it was written by one person, but these writing experts from the intelligence bureau can simulate the handwriting of almost everyone. In order to test the abilities of these special talents, Tan Xiaopei even asked a writing expert to impersonate his handwriting to write imperial edicts and some other things and send it to close ministers... As a result, among the fourteen documents in three days, only Huang Xuping recognized the handwriting of the impersonation. However, Huang Xuping himself was a master of calligraphy and painting, and had a certain understanding of such subtle things. No one else recognized him as a ghostwriter.

However, the Intelligence Agency's research on other forensic sciences is not good. The invention and development of photography technology have given the Intelligence Agency more powerful tools in many businesses, but at best, it is to cooperate with drawing techniques such as sketching and sketching to train some portraitists and establish a preliminary investigation and search comparison system for intelligence officers from various countries. In other aspects, it is blank. In Ye Tao's mind, the most magical thing in forensic sciences is not these contents. Whether it is handwriting or face, it is just the foundation. You can only understand whether it is this person and who the person is.

, cannot understand what this person did. The magical trace technology can do this, which can provide intelligence personnel and criminal case investigators with more foundation for thinking and reasoning. The identification and comparison of fibers, hairs, particles, etc. are all part of this mysterious trace science. These require huge database accumulation, long-term data collection, and long-term professional training, with a solid professional foundation and a keen mind. Ye Tao and Tan Weixin spent three days to summarize a full ten books in separate oral statements.

The content of 50,000 words describes the forensic science, including trace science, and even fingerprint comparison and other content. Ye Tao even easily developed a set of tools to collect fingerprints. This thing came to Nie Rui's hands, making Nie Rui and the people around him almost forget the most important things in their hands in a short period of time. There are many criminal investigation experts drawn from local government offices in the Intelligence Bureau. They can piece together the case and find the real murderer through those details, but no one can classify such a complex system to such a subtle level. Fingerprint comparison is something that everyone has never thought of.

Some staff members around Rui insisted that if fingerprints alone could be put into practice, they could at least increase the rate of solving ordinary criminal cases by 30%. You should know that the tools provided by Ye Tao not only can extract fingerprints from smooth surfaces, but also include some tools to extract fingerprints on complex surfaces. Ye Tao and Tan Weixin realized all the knowledge they learned in the series of American dramas that "crime scene investigation" back then. He was powerless to do anything like computer comparison, but it was very simple to evaporate and adsorb the particles of glue to present fingerprints on complex surfaces.

Ye Tao naturally knew that even if this pile of things is implemented from now on, it must be practical, and it will not be thought about in a few years. This time it was taken out just to allow the Intelligence Bureau to start cultivating a group of talents and give them preliminary internship opportunities. The most important thing this time will be the recording technology that has just been released.

The recording technology has been developed in the Yeshi Workshop Research Institute for several generations. Now, it has finally achieved good performance in terms of reliability, ease of use, etc. The earliest recording technology was the dense wax tube. Although the Yeshi Workshop's level in precision parts has reached a considerable level, it cannot solve the defects of the material itself after all. The sound receiving end of the dense wax tube recorder uses a paper basin, which does not involve the circuit at all. Instead, relying on an extremely slender probe, the sound vibration sensed by the paper basin is transmitted into a control box, and the sound vibration sensed by the paper basin is transmitted to a control box.

The dynamic amplification of the dots depicts this dynamic on the dense-shaped wax cylinder rotating at a constant speed. Although this thing can almost be called the show of precision mechanical processing technology, it is terrible in terms of recording effects. The recorded sound is blurred and disturbed by noise, or the sound is strong and fluctuating, and it will not work properly, leaving a string of screaming sounds on the wax cylinder. In addition, the life of the dense-shaped wax cylinder is very short, and it will not work after a few replays, which greatly reduces the practicality of this technology.

The second generation of recording technology is much better. The institutes of the Institute's Electrical Workshop discovered the sound excitation effect and developed the first generation of mixed ore sand sound probes, which was very good. The collected sound was amplified and then firmly portrayed on the bakery master disk. However, this second generation of recording technology has a big problem, that is, the sound signal is amplified in the mechanical section, and the distortion is very strong. But after all, through this second generation of technology, the workshop has already had basic ideas, the material of the master disk, the sound probe technology, and even developed the technology of copying with the master disk. Although the copied disk is always a little different from the master disk when it is played back, the quality has become more and more stable and reliable.

At this time, Ye Tao decisively intervened in the research. Ye Tao had nothing to change for the sound probe. This sound probe may be a little larger in size. The most exquisite trial product is as big as a microphone, but it is completely available, and the accuracy is also surprising. Ye Tao understood that the bottleneck of the recording equipment this time is that the researchers do not have the knowledge and experience of circuit design. Ye Tao directly guided the basic transistor manufacturing, developed the first and second generation transistors, and began to popularize the knowledge of circuit design. The third generation of recording equipment was born. Although there were slight improvements in sound acquisition and master engraving technology, in general, the third generation of recorders and the second generation were developed in history, but in the middle, there were earth-shaking changes.

After the sound is collected and becomes an electrical signal, it is transmitted to the master engraving mechanism after two layers of filtering and three-pole amplification. Although such a recorder is a little larger and needs to accommodate many transistors, the design idea is already very mature. The recorded sound is only slightly distorted, but it can already distinguish the speaker of the voice, and the recording of animal calls can also distinguish the specific types, which has great practical value. After the design idea is mature, the research institutes in the workshop were stunned and quickly made various improvements. As the transistor production process matured, the volume reduction cost decreased, and as the research institutes absorbed the recording device and strengthened it.
