Problems solved by technology
In most cases, the actual use state of the reflector is neither the optical axis horizontal nor the optical axis vertical, and thus it is impossible to quantitatively detect and analyze the imaging quality of the photoelectric load in this state. So far, a simple structure, It is necessary to have a mirror attitude transformation surface shape detection device that is easy to operate and reliable in operation

The present invention relates to the field of photoelectric measurement technology, and specifically discloses a device for detecting the attitude transformation surface shape of a mirror. The detection device includes: a body, a first linear platform, a second linear platform, a third linear platform, an airbag Turntable, second turntable, third turntable, 4D interferometer and CGH compensator; by sending commands to control the first linear platform, the second linear platform, the third linear platform, the first turntable, the second turntable and the third turntable, so that When the 4D interferometer, CGH compensator and the measured mirror assembly move to the required pitch angle and roll angle respectively, and meet the appropriate air separation and eccentricity requirements, the surface shape of the mirror in this state is tested. Interferometry: The detection device of the present invention can perform dynamic real-time detection of the mirror surface shape under certain pitch and roll angle working conditions, and has the advantages of simple structure, convenient operation, low cost and strong versatility.
Description
technical field [0001] The invention belongs to the technical field of photoelectric measurement, and in particular relates to a detection device for attitude transformation and surface shape of a reflecting mirror. Background technique [0002] When the aviation airborne photoelectric turret is tracking and aiming at targets on the ground or at sea, the photoelectric load installed in the photoelectric turret will be affected by the gravity under the change of the aircraft's flight attitude. Taking the Cassegrain optical system as an example, because the primary mirror has a relatively Large and heavy, when the inner frame is pitching and rolling, the surface shape of the primary mirror changes due to the angle between its optical axis and gravity, which affects the imaging performance of the photoelectric load. [0003] One of the current methods of measuring the surface shape of the mirror is to build a horizontal detection optical path, that is, by placing an interferome...
