For the first time in China!"Manufacturing Xi'an" has won a number of technical breakthroughs again

A few days ago, the reporter learned from the Xi'an Optical Machinery: After one month of rail testing, the "Innovation X" series of "Innovation X" series of "Innovation X" series (Space New Technology Test Satellite) worked normally and equipped by the General Innovation of the Chinese Academy of Sciences The load carried out the test according to the plan and obtained the first batch of scientific results. The all -aluminum free curved camera (FAIT) developed by Xi'an Optical Machinery (FAIT), as one of the first star loads of the "Innovation X" series, has achieved a complete success in the rail test. The new optical imaging system of the "All -Aluminum Light Machine+Freedom Turbine" was implemented in the rail performance verification, and many technical breakthroughs were obtained.

According to the scientific researchers of Xi'an Optical Machinery Institute, all the lenses of FAIT use free curved surface types to replace traditional spherical or non -spherical lenses, fully release the degree of optical design freedom. Under the constraints of the same volume and space layout, the optical system imaging quality is improved than traditional design. Nearly 10 times.

At the same time, FAIT also innovatively adopts the full aluminum optical mechanism, that is, optical lenses and mechanical structures use the same aluminum alloy material to replace the traditional "glass lens+optional structure" optical mechanism type. According to reports, the all -aluminum light machine has the advantages of low cost, short manufacturing cycle, and no thermalization. The whole machine is not sensitive to changes in the environmental temperature, and the camera imaging quality has not changed significantly when the measurement temperature deviation of the rail measurement is 30 ° C, which greatly reduces temperature. Control needs. In addition, the all -aluminum light machine can also work under extremely low temperature conditions, similar to the Weber telescope, which helps to achieve high -sensitivity detection of weak infrared targets.

After years of research, the scientific research team of Xi'an Optical Machinery Institute has broken through a number of core key technologies such as free curved surface design, processing, testing, and assembly. The performance of the core optical components and optical systems has reached a high international level. The successful completion of the FAIT testing task in the orbit is an important symbol of the metal free curved optical imaging technology of the Xi'an Optical Machinery Institute from the basic research to the engineering application. It can provide important technical support for solving the problem of optical load detection and imaging performance improvement in my country. In the future, it is expected to carry out innovative applications in important areas such as high -resolution of ground remote sensing, high -efficiency and high -sensitive space target detection, and optical load large -scale networking.
