As a non-destructive testing method, optical technology plays an important role in the discovery, recording, extraction, inspection, identification and preservation of physical evidence. The main task of the criminal imaging technology is to use advanced optical technology to obtain image data related to physical evidence, to obtain clear images of physical evidence by means of distinguishing substances, and to dig deep into the evidence information that can reveal the truth of the case.

The opportunity to combine. </p></p><p></p><p ><p > At present, the research on spectral imaging technology of the Ministry of Public Security's Physical Identification Center has been funded by five national research projects and funded by one ministerial research project. . At the implementation stage of the National Science and Technology Support Plan of the “Eleventh Five-Year Plan” and the “Twelfth Five-Year Plan”, the research linkage and sustainability research situation have been successfully realized. Based on the above achievements and future development trends, the Ministry of Public Security's Physical Identification Center and the China Academy of Engineering Physics and Sichuan Shuangli Hepu Technology Co., Ltd., a subsidiary of Zhuoli Hanguang, jointly established a joint laboratory for multispectral imaging detection technology, which will further promote Promote the application of multi-spectral imaging technology in the field of criminal investigation. Based on the joint laboratory platform, spectral imaging test standards and evidence database and data analysis network server will be gradually established. </p></p><p align="center" ><p ><img align="absMiddle" alt=

Scope of application:
Through research, the spectral imaging technology can be applied to many professional work in the field of evidence identification, such as trace inspection, document inspection, trace material verification, and biological evidence discovery. It is precisely because of the strong applicability of spectral imaging technology that it reflects the value of this technology and the potential for popularization.

Bimetal Thermometer

Bimetallic thermometer combines two metals with different linear expansion coefficients, and one end is fixed. When the temperature changes, the thermal expansion of the two metals is different, which drives the pointer to deflect to indicate the temperature. This is bimetallic sheet thermometer, as shown in the figure on the above page. The temperature measurement range is - 80 ~ 500C, which is suitable for temperature measurement when the accuracy requirement is not high in industry. As a temperature sensing element, bimetallic sheet can also be used for automatic temperature control.
