Description of an Infrared Zoomcollimator (Beschrijving van een Infrarood Zoomcollimator)

Abstract

The performance of thermal imagers is generally tested by means of test targets, put in the focal plane of a collimator. For MRTD measurements bar targets are used with a certain frequency and variable temperature contrast. The zoomcollimator, described in this report provides a variable spatial frequency, which is more comparable to the range variation of a target in the terrain with certain size and temperature contrast. In the focal plane also a line source and a circular source with variable temperature contrast can be used, in order to measure the MRTD in an objective way conform the method, developed at TNO-FEL
