Calibration device and calibration method for arc-shaped infrared target simulator

Abstract

A calibration device and a calibration method for an arc-shaped infrared target simulator belong to the technical field of infrared target simulators. In order to meet the needs of existing technologies, the device includes: an arc-shaped infrared target simulator, a high-precision adjustment mechanism, and a test base , infrared goniometer and tripod bracket, the high-precision adjustment mechanism is located on the test base, and the arc-shaped infrared target simulator is fixed on the high-precision adjustment mechanism; the infrared goniometer is placed at a certain distance behind the arc-shaped infrared target simulator , installed on a tripod bracket, and at the same height as the optical axis of the arc-shaped infrared target simulator; Calibrate the target points generated by the infrared target simulator; the scheme can effectively reduce the aiming error caused by the change of the light and dark gray level at the edge of the target arc by presetting the circular hole above the target arc; the operation is simple, Calibration work can be done directly indoors.
