Paper Abstract

This paper discusses a common reflective collimator approach to the alignment and testing of laser ranger/designators and thermal imaging systems mounted on common carriers. All test measurements are made at a common focal plane. A large aperture reflective common collimator is capable of testing multispectral systems independent of configuration as long as the total aperture of the system to be tested is less than the aperture of the collimator. An analysis of the test system capabilities with respect to measurement of imaging system performance, boresight of imaging system or laser receiver to laser transmitter, and measurement of laser transmitter parameters is outlined. A shearing plate technique for accurate focusing of the test collimator is discussed. The shearing plate technique is suitable for field use and can provide a focus accuracy on the order of tens of microradians.
