由浙江大学研制成功的激光高速全息摄影装置,是一种分幅式脉冲全息摄影装置。它采用时序脉冲选模红宝石激光器作相干光源和声光偏转器作快速高精度定位分幅装置。本装置兼有脉冲全息摄影和一般高速摄影的功能,因而适用于瞬态光力学、快速事件激光干涉分析、非稳态流体力学等方面,成为一种新型测试手段。该装置稳定拍摄频率为4万幅/秒,分幅数4(改变光学系统后能一次获得8幅分
Developed by Zhejiang University laser high-speed holographic device, is a fractional pulse holographic device. It uses time-pulsed mode selection ruby lasers as coherent light sources and acousto-optic deflectors for fast, high-precision positioning of framing devices. The device combines the functions of pulse holography and general high-speed photography, so it is suitable for transient photomechanics, fast event laser interference analysis, unsteady fluid dynamics and so on, becoming a new type of testing method. The device stable shooting frequency of 40,000 / second, the number of sub-4 (after changing the optical system can be obtained at a time eight points
