Abstract

Diffractive optical encoders have quickly established themselves in the marketplace because of their small seize, high accuracy and relaxed alignment tolerances, but current products are still composed of carefully packages, discrete optical and electro-optical components. MicroE and Digital Optics Corporation have been working together on the next generation of these encoders, which replaces all discrete and refractive elements with DOE's and more completely integrates the requisite optical and electro-optical components. In this paper we describe a monolithic source/optics/detector encoder module we have designed and prototyped for a satellite application under a NASA Phase I SBIR contract.
