title: Interferometric phase measurement using pyroelectric vidicons.
abstract: Infrared interferometry is used for testing both infrared materials that are opaque in the visible and optical surfaces still in the ground-glass condition. A pyroelectric vidicon is used to detect infrared interference fringes, which can be phase shifted, allowing precise measurements of the infrared wavefront. This paper discusses the pyroelectric vidicon as a detector of infrared interference fringes and the limitations it presents when used to obtain accurate phase-shifted measurements of an infrared optical wavefront.
