Abstract

This paper describes a technique for verifying with high accuracy and repeatability the alignment of optical components and subassemblies. Using as an example the work done at Martin Marietta Electronic Systems to implement the testing of an optical laser pattern encoder operating in conjunction with a zoom optics and a CO2 laser, we show how relatively simple alignment tools simulating optical components can be utilized, both in the laboratory and in the factory, to position the components on their test beds and predict their performance prior to installation in the system. This simulator method can shorten dramatically the time required to align, check-out and troubleshoot optical components.
