局部参考光束全息图的形成及应用

Local reference beam generation for holography and its applications

在记录全息图时，如果用连续输出的激光器作为照明光源，就必须使用防振性能很好的防振台。在一般情况下，激光器和全部的光学装置都安放在防振台上，被摄物体也必须置于台上。然而，由于防振台不便移动，而有些被摄物体又无法进入实验室和置于防振台上。

The principle and the method of local reference beam generation for holography are described. A 35mm portable holographic camera developed by the authors is taken as an example to show the feasibility of the principle. It has been proved that this holographic camera has the ability to diminish the effects of disturbances on holography recordings and some experimental results are presented.
