Abstract

This document describes the simulation principle, outlines the design procedure of the projection optics system from predesign to achromatization. The Optical system collimates output from Liquid crystal light valve in 8~12μm and enables an imaging system to be tested out of 20°field of view. The effective focal length of this F/1.5 system is about 113mm. There is sufficient exit pupil distance to match projector exit pupil to the LWIR imagery system entrance pupil. A long working distance between Liquid crystal light valve and the optics system is approximately 120mm. The Modulation Transfer Function (MTF) and the geometric blur spot for three-field position repenting an on-axis point, a full field and an intermediate point show the better performance of the optical system.
