This applet allows users to simulate standard optic elements (lens, mirror, dielectrics, sources, apertures) and observe the ways that light rays propagate through these elements. The applet is designed to be scripted but may also be used to construct optical systems using buttons and a click and drag metaphor.

Thermal Resolution Specification in Infrared Scene Projectors 2015 (PDF)
Infrared scene projectors (IRSPs) are a key part of performing dynamic testing of infrared (IR) imaging systems. Two important properties of an IRSP system are apparent temperature and thermal resolution. Infrared scene projector technology continues to progress, with several systems capable of producing high apparent temperatures currently available or under development. In this paper, we discuss some of the various factors that affect thermal resolution of a scene projector system, and propose some specification guidelines regarding thermal resolution to help better define the real needs of an IR scene projector system.
