本文设计了一套光路,以不同入射角照明的振动物体,可以以不同的参考光记录在同一张全息干版上,形成重像记录。当分别以原始参考光反演时‘可依次看到外廓完全相同,条纹分布却不同的时间平均全息像。将其翻拍成普通照片后,可对负片或正片进行图像和数据处理。照明光源采用点光源,在建立适当的坐标系后,可以方便地根据图片计算出振动物体表面任一点的振幅的三个分量。如果没有图象数据处理系统,可以由人工采集数据,由计算机进行计算。
In this paper, a set of optical paths, vibrating objects illuminated at different angles of incidence, can be recorded on the same holographic plate with different reference lights to form ghost images. When the original reference light, respectively, when inverted ’can be followed by the outer contour of the same profile, but the distribution of different temporal average holographic image. After it is remade into normal photo, the negative and positive images and data can be processed. Lighting source using point light source, the establishment of a suitable coordinate system, you can easily calculate the image based on the vibration of any point on the surface of the three components of the amplitude. Without the image data processing system, the data can be collected manually and calculated by the computer.
