Paper Abstract

This paper describes the design of test equipment constructed to enable the Marine Corps Logistics Base the capability to provide the required optical/IR boresight and electronic tests for rebuild and TOSH (TOW optical sight hardening) modification for the TOW (tube launched, optically tracked, wire guided) guided missile launcher optical/infrared sight. Optical modification and calibration are performed to improve system accuracy and reliability against failure, especially in a battlefield environment. Although principle concern was for the day sight, provision for the thermal night sight was also included. This design includes a large diameter optical beam, provision for thermal targets and night sight boresight alignment capability with the day sight. Primarily, a specially constructed collimator test set is discussed, implemented as the TOW 150 test and alignment station. In addition, a precision TOSH prism test system is briefly described, which is used to facilitate internal optical component boresight alignment utilizing a HeNe laser, alignment telescope and video camera. Radiometric theory is applied to the collimator geometry, which includes the modulation factor, Planck radiation function and appropriate bandpass integrated to yield effective rms irradiance values for calibration of the day sight.
