Abstract

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.

摘要

一种最初为光学计算而开发的快速铁电液晶空间光调制器，在振动测量中找到了新的应用。提出了一种振动同步双曝光全息干涉测量的新方案，该方案充分利用了铁电液晶空间光调制器的速度。进行了初步实验，这些实验证明了几乎连续的实时振动测量数据采集。
