Abstract
This paper describes a noncontact and computer compatible test setup to calibrate the angular motion of a life test model of a scanning mirror mechanism using a lateral-effect position sensitive photodetector (LPSD). Laser based measurements of its movements using the LPSD adds up the suitability of this mechanism to very high resolution radiometer effectively. The description of the scan mirror mechanism and the existing calibration test methods are briefed. The characteristic properties of the LPSD are discussed. Experimental details and the results obtained are presented.
