Design of the Optical System for Infrared Dynamic Scene Simulation

Chen Hui-ling

Open publisher page 1 citations

Abstract

This document describes the simulation principle and 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 image 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 projector is approximately 120mm. The Modulation Transfer Function (MTF) and the geometric blur spot for three-field position represent an on-axis point, and a full field and an intermediate point show the better performance of the optical system.
