65438-0965, Academician Huang Shanglian founded the research field of metrology grating technology in Chongqing University. He presided over the successful development of hydraulic long grating dynamic mask aligner and GSX-2 long grating displacement digital display device, and won the second prize of Chongqing major scientific and technological achievements 1979. Because of its outstanding achievements in grating manufacturing and application, it won the second prize of scientific and technological achievements in Chongqing, Sichuan Province in the same year.
Starting from 1976, QGK405 high-precision photoelectric circular engraving machine was developed, and a new theoretical system for improving the accuracy of grating angle measurement system was put forward. Innovative technologies such as total receiving of annular optical fiber bundle, high-precision aerostatic shaft system and self-adjusting speed system were comprehensively adopted, reaching the international advanced level that the accuracy of grating disk is better than 0. 1 angular second, and obtaining the national/kloc-0. The theoretical system of grating angle measurement system to improve the accuracy of angle measurement won the second prize of scientific and technological progress award (theoretical achievement) from the State Education Commission 1996.
Academician Huang Shanglian also invented the scribing technology of arbitrary binary circular grating, and successfully developed a high-precision real-time detection system for circular grating. The photoelectric shaft encoder series developed by him has been commercialized and widely used in China, and this achievement won the second prize of scientific and technological progress of the State Education Commission 1995.
Academician Huang Shanglian is the academic director of metrology grating technology in Chongqing University. Its research achievement "Absolute Zero-length Grating Displacement Measurement System" won the third prize of 1998 National Science and Technology Progress Award and was listed as a major national new product promotion project. The coarse grating measurement system won the second prize 1990 of the state education commission for scientific and technological progress, and was listed as a national torch plan project.
Academician Huang Shanglian presided over the successful development of the international advanced single-mode optical fiber welding machine (Seventh Five-Year Plan), which has been mass-produced. Responsible for the research and development of polarization-maintaining optical fiber welding machine in the 863 project of the Ministry of Space, and has been delivered for use. 1984- 1990, academician Huang Shanglian instructed students to engage in handwritten character recognition research. Participated in the overall design of the automatic form reader, guided students to complete the research of the national 863 project AV- 100 automatic form reader, and achieved international leading results, which were successfully applied to the fourth national census, making China the first country in the world to use handwritten character recognition technology on a large scale in the census. This achievement won the third prize of 1995 National Science and Technology Progress Award and was affirmed by the United Nations Statistics Bureau.
Academician Huang Shanglian invented an intelligent processing method for complex forms, which can directly process black forms, and this method has obtained a national invention patent. And instructed doctoral students to complete the complex form processing and character recognition system, which has been actually used in the processing and recognition of national family planning forms. Academician Huang Shanglian led and participated in the organization and implementation of the torch program of automatic form reader. Automatic meter reading machine has been widely used in statistics, family planning, education, civil affairs and public security departments. Academician Huang Shanglian initiated the research direction of distributed optical fiber sensing system in China. 65438-0987 went to England to study optical fiber sensing technology. After returning to China, he presided over the Eighth Five-Year Plan, the National Natural Science Foundation and the Doctoral Program Fund of the State Education Commission, and also completed the national key project of optical fiber pressure sensor and undertook the Eighth Five-Year Plan project of optical fiber flowmeter. The research group headed by Academician Huang Shanglian has done creative research, put forward a perfect Raman temperature sensing theory and developed a distributed optical fiber temperature sensing system. The mode coupling theory of high birefringence fiber under transverse force is established, and a distributed fiber force sensor system is developed, and the application effect is obtained. A distributed optical fiber stress measurement system based on heterodyne detection and a quasi-distributed optical fiber application variable measurement system with core Bragg grating are proposed, and their feasibility is verified by experiments. An optical fiber sensor array and neural processing system for intelligent structure condition monitoring are proposed, and they are embedded in concrete structures for testing, revealing some important phenomena.
