A fast ferroelectric liquid-crystal spatial light modulator,
originally developed for optical computing, has found a new application
in vibrometry. A new scheme of vibration-synchronized
double-exposure holographic interferometry is proposed that makes full
use of the speed of the ferroelectric liquid-crystal spatial light
modulator. Preliminary experiments were performed that demonstrate
virtually continuous real-time vibrometric data acquisition.
