Abstract

Stray light in optical systems is usually assessed by techniques which are essentially similar to those used in the design synthesis of the system. In general however the dimensionality of the actual build of the system is far higher than that of the design and the traditional 'ray tracing' assessment techniques can become unmanageable. Modern computer graphics software developed for CAD and the entertainment industry has been applied to this problem at Pilkington Optronics as part of the process of integrated optomechanical design. This paper describes the relevant features of the new software packages as applied to the analysis of stray light and presents some results from particular systems. A useful feature of the technique is the use of animation to reduce the dimensionality; these examples cannot be presented here in written form but some simplified examples are available on request on 3.5 inch diskette format.
