AI Technical Summary
Traditional fast reflector testing methods are difficult to guarantee measurement accuracy under high and low temperature, vibration and vacuum conditions, and the measurement bandwidth of photoelectric autocollimators is low, which makes it difficult to meet the dynamic performance test requirements, resulting in large errors.
A three-channel laser interferometer and probe mounting fixture are used to synchronously collect distance data from three measurement points on the surface of the fast reflector under test through the interferometer probe. The pitch and azimuth angles are calculated to generate dynamic and drift characteristic test results. The device is designed so that the probe is in a thermal vacuum environment, while the host and computer are externally connected to ensure the continuity of the measurement link.
It improves the testing accuracy and objectivity of dynamic performance evaluation of fast reflectors in multiple environments, reduces the impact of its own sensor error, and meets the testing requirements in vacuum scenarios.
