用实时全息术研究低速变化过程的一种简易系统

研制了一种用于研究物体低速过程的简易系统，它由带有液门原位化学处理的实时全息干涉装置和具有连拍功能的相机以及一台氦氮激光器组成，是一种简易实用的“低速、实时全息干涉摄影系统”。用它记录了火箭推进剂样品在室温，常压下的燃烧过程，１００瓦普通只灯逐级加压的点燃过程，对实时全息图的记录和处理采用了一种可获得高反衬度的新技术，拍摄的成功率高，干涉条纹的反衬度好，它为研究物体的低速变化过程提供了一种有力的手

A Simple System for Studing Low Speed Phenomena with Real Time Holographic Interferometry

A simple system for studing low speed phenomena by using holographic interferometry has been developed in our lab. It can be used to analyze the real time interference fringes with the combination of a real time holographic interferometry and a camera with continue shooting function and a He Ne laser. A series holographic interferograms of combustion process of an solid rocket propellant sample and a series holographic interferograms of lighting an incandescent lamp by increasing the voltage of the lamp step by step were recorded successivelly by using this system. The higher rate of the success for the holographic recording and the higher contrast for the interference fringes have been obtained by this system. It can be used as a powerful approach for studing low speed phnomena function.
