Embodiment 1
[0076] The tracking accuracy measuring instrument calibration device in this embodiment includes a collimator array 1 and a tracking accuracy detector 2, and the system schematic diagram of the calibration device is as follows figure 1 shown. When calibrating, firstly, adjust the plane of revolution of the tracking precision testing equipment to coincide with the plane where the optical axis of the tracking precision measuring instrument calibration device is located; then, the tracking precision testing equipment starts to move, and the focal plane of each collimator in the tracking precision measuring instrument calibration device The detectors in turn record the moment when the light source of the tracking accuracy test equipment hits the detector, and calculate the angular velocity information of the tracking accuracy test equipment according to the angle information calibrated in advance for each detector and the moment when it is illuminated.

The invention belongs to the technical field of optical metering and measurement, and particularly relates to a calibrating device for tracking precision measuring instrument, comprising a collimator array, a tracking precision detector group, a precision adjustable shafting and a computer acquisition and processing system. The collimator array is used for receiving, aligning and distortionlessly focusing optical signals emitted by the calibrated tracking precision measuring instrument, and converging the optical signals to a photosensitive surface of the tracking precision detector group. The tracking precision detector group is used for detecting optical signals from the collimator array and converting and outputting electric signals. The precise adjustable shafting is used for carrying out supporting and high-precision adjustment on the collimator array and the tracking precision detector group. The computer acquisition and processing system is used for collecting the electric signals output by the tracking precision detector set and conducting data analysis processing and storage. The device has the main functions and characteristics of wide operating wavelength range, large dynamic range, accurate measurement of tracking precision characteristic parameters and the like, and meets the measurement and calibration requirements of a weapon model photoelectric system tracking precision measuring instrument.
Description
technical field [0001] The invention belongs to the technical field of optical metrology and measurement, and in particular relates to a calibration device for a tracking accuracy measuring instrument. Background technique [0002] The photoelectric search and track system is an optoelectronic weapon platform that integrates optical search, tracking and aiming functions by installing infrared thermal imaging cameras, visible light televisions, and laser ranging and pointing systems on two-axis or multi-axis gyro-stabilized platforms. Tracking accuracy is a key parameter to evaluate the tracking ability of military electro-optical search and track system. At present, there are mainly two types of representative methods of tracking accuracy measuring instruments: semi-physical simulation test method and on-site shooting test method. Some units also use single parameter test and theoretical calculation to give the tracking accuracy of the whole system of the military photoelect...
