Design, Development and Testing of a Prototype Optical System for a Next Generation Multiplexed Imager

Abstract

A proof-of-concept experimental validation of a proposed idea for a prototype optical system was conducted. This system will be incorporated into a new type of infrared, optically multiplexed imaging and multispectral imaging system. This system will use two-sided, transmitting-reflecting encoding Walsh masks to form a two-dimensional optical Kronecker product. First, a ray tracing design was made to model the optical system. Then the optical system was prototyped and ronchigrams were photographed to document the aberrations present in the optical system. It was shown that spherical mirrors could be used to accurately reimage an object onto the encoding masks without significantly affecting the optical accuracy of the image. The geometric aberrations resulting from this design did not significantly effect the overall ability to produce the Kronecker product. Multiplexed Imaging; Optical Design
