| 摘 要： | 根据通讯论和信息编码理论,基于莫尔变换效应,本文提出了两种位相测量方法.第一种是载频干涉法,它有许多不同的应用和优点,如波面的自干涉和互干涉、多重记录、波前剪切、谐波干涉等等;第二种是用白光的(编码板)照相干涉法.它们能用于强变化位相体的测量.

Moire transformation and phase measurement(Ⅰ) |
| |
| Abstract: | The moire transformation was analysed using communication theory. Based on it, we proposed two new types of phase measurement. The first is a carrier interferometer. It has various applications and advantages, for example, automatic compensation, multiplex recording, shearing of a wavefront, relative compensation of the phase variation in dynamic texts, harmonic interference, etc. The second is a coded mask photographic interferometer using white light. It can be used for measuring strongly varied phase objects. |
