Abstract

A major area of concern when designing infra red systems is the defocus effect caused by the variation in temperature of the system from ambient. This paper outlines how this defocus affects the performance of the system and discusses in some detail techniques for overcoming this problem. The advantages and disadvantages of each technique are identified and a trade-off matrix shows the relative merits of each.
