Image Holographic Method for Measurement of Bubble Field

本文对用象全息方法测定气泡场的有关问题进行讨论。除对光路系统设计、全息图的再现及观测方式等进行简单介绍外,着重分析了象全息的视场受限问题及其解决方法。

Image holography was used to record and reconstruct bubble field. Using specific properties of image holography, some shortcomings existed in ordinary holography can be overcome, and some additional benefits are obtainable. Experimental results show that the image holography is very convenient and practical, and bubbles of micrometer level can be measured. The image lens in optical circuit of image holography may perform an undesired function as a field spot, limiting the visual area of reconstructive image: This problem is analyzed in detail. Other problems concerned such as design of optical system are also discussed.
