研制了一种用于研究物体低速变化过程的简易系统。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氖激光器组成，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瓦普通白炽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段 A simple system for studying the process of low speed change was developed. It consists of a real-time holographic interferometer with liquid-in-situ chemical processing and a camera with continuous shooting and a He-Ne laser. It is a simple and practical “low-speed, real-time holographic interferometric photography system.” Use it to record rocket propellant samples at room temperature, atmospheric pressure combustion process; 100-watt ordinary incandescent light step-by-step ignition process. Real-time hologram recording and processing using a new technology to achieve high contrast. High success rate of shooting, interference fringes contrast good. It provides a powerful tool for studying the slow changing process of objects
