A New, Semiautomatic Interferogram Evaluation Technique

Source

A new, semiautomatic interferogram evaluation technique is discussed. The technique format is based on an interference pattern displayed on a closed-circuit television monitor.

Comparative results using this technique, a computer evaluation, and several manual techniques, including the ASTM Interpretation of Interferograms of Nominally Plane Wavefronts (F 529-77 T), are presented.
