Paper Abstract

The forward tracing technique for diffraction analysis (FFTD) is a numerical technique for ray-tracing environments inspired by the Boundary Diffraction Wave. The technique was developed specifically considering circular apertures in imaging systems. In previous work the technique was applied to a simple optical system. The value of the method has been geared towards aiding optical design where diffraction effects not produces at the aperture stop are important. In this work the technique is applied and evaluated as a tool for analyzing a complex system where only circular apertures are present. The chosen system is an IR endoscope on the MWIR region. The system requirements make for circular apertures aside from the stop where diffraction becomes important. FFTD is applied for obtaining irradiance information at the image plane. The key parameters affecting the simulation are described on axis and field.
