Paper Abstract

The construction of scanning wide-angle Michelson interferometers using existing field compensation methods1)2) is difficult and costly, especially in the visible region 3)4). The new stigmatic field-compensation method5)used in the current scanning wide-angle Michelson interferometer, overcomes the barrier of the high degree of synchronized motions that are required by Mertz's First Method- 5). A dynamic alignment system was also developed for the instrument to keep the two mirrors of the interferometer parallel during a scan. The operation of the instrument is controlled by a computer in real time.
