Abstract

Using a single focal parabolic reflector of an intensity interferometer(II) system is simulated. The extent that focal properties amongst a parabolic reflector can change the statistics of the light at a detector is analyzed. Recent technological advances have increased the speed and sensitivity of photon detectors, developed large scale precision optics, and incorporated multi-spectral imaging techniques which have led the way to reexamine the usefulness of II for scientific measurements. A ray tracing algorithm is used to examine how the statistical variations of simulated monochromatic stellar light changes from the source to the detector. Changing the position of the detector from the focal plane and changing the surface profile of the mirror develops a metric to understand how the varying scenario’s affects the statistics of the detected light. Photon streams are evaluated for light distribution, time of flight, and statistical changes at a detector. This research and analysis is used as a tool to develop a metric to quantify how structural perturbation effect the statistics of photon stream detections inherent in II instrumentation and science.
