Earth simulation device for testing optical detectors obtained national patent

[China Instrument Network Instrument Development] In the aerospace field, satellites and spacecraft need to use the Earth as the reference object to determine their posture in outer space, and they must rely on optical detectors to identify the extraterrestrial contour at different orbital heights to obtain The required data.

When performing simulation tests on the ground, the performance indicators of the optical detectors must first be tested and verified. Therefore, an earth simulation device for testing optical detectors needs to be established.

Xi'an Institute of Optics, Space Room Lin Shangmin, Wang Hu, and Liu Jie invented an earth simulation device for testing optical detectors, which is simulated on the ground by a multi-dimensional combination platform, a light source, a reference mirror assembly, and an earth model shell combination. The working environment of the optical detector, the performance of the optical detector to verify the performance of indicators to solve the problem during the ground simulation test of the optical detector performance indicators to test and verify the problem.

The structure of this device is simple and stable, it is not easy to be deformed, and it is easy to disassemble and disassemble the parts. It has been authorized by the national invention patent.
