Stepped strobe phase CAH technique for measuring vibration amplitude and phase

A new technique for measuring spatially dense vibration amplitude and phase using stepped optical phase dual reference double exposure or real time computer aided holometry (CAH) methods along with phase stepping of a strobed laser beam has been developed. The technique is called `stepped strobe phase' and is analogous to the `stepped optical phase' technique. The theory and experimental results are presented.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
