摘要:
A procedure has been developed for determining the gross refractive index variations in infra-red transmitting materials. The technique uses an infra-red interferometer operating at 10·6 μm, with a pyroelectric vidicon (or any other suitable T.V. compatible) fringe visualization device, interfaced to a digital T.V. frame store. Representative examples of the results obtained are shown.
