一、概述应用激光全息照相显微技术,可以在极短的曝光时间内制得样品的全息照片。这全息照片记录了样品的所有的三维特点,样品不需要特别制备,更不需要象用普通显微镜观察时那样要将样品制得很薄,以便使样品在观察时不在焦点内外漂浮。这种全息照片可以在很大景深范围内观察,而且观察到的再现象是立体的。并具有很高的放大倍数、 First, an overview of the application of laser holographic microscopy, samples can be made in a very short exposure time holographic photos. This hologram captures all three-dimensional characteristics of the sample. The sample does not need to be specially prepared and does not need to be thin enough to look like an ordinary microscope so that the sample does not float in and out of focus when viewed. This hologram can be observed over a large depth of field, and the observed reappearance is three-dimensional. And has a high magnification,
