Paper Abstract

Miniature optical correlators provide a means of portable real-time pattern recognition. Most of the attention has been given to reducing length with little consideration to system robustness. Although it is recognized that aberrations will limit system performance, more critical limitations are alignment and sensitivity considerations. This paper presents a procedure for the design of a short robust optical correlator. Theoretical limits on system miniaturization are restricted to component availability; however, practical limitations are dictated by physical constraints and alignment tolerances. This paper explores engineering trade-offs among length, alignability, aberrations, and system reliability. In addition, a complete system analysis including performance, aberrations, and sensitivity is presented.
