Abstract
A fast ferroelectric liquid-crystal spatial light modulator, originall y developed for optical computing, has found a new application in vibr ometry. A new scheme of vibration-synchronized double-exposure hologra phic interferometry is proposed that makes full use of the speed of th e ferroelectric liquid-crystal spatial light modulator. Preliminary ex periments were performed that demonstrate virtually continuous real-ti me vibrometric data acquisition. (C) 1998 Optical Society of America.
