| 摘 要： | 本文提出了利用介质表面反射实现光学图像相减的一种新方法．利用P光与S光在光疏-光密界面反射时产生的相位改变，可在两幅图像间引入π位相差，使之相同部分的图像相消，只留下差异部分，从而实现图像相减．本文介绍了工作原理并给出了实验例证，证实利用该方法有稳定性较高的π相移产生，验证了这是一种简便、实用、有效的途径． |

| Abstract: | In this paper, a method of optical image subtraction using reflection from the media surface is presented. With the phase change of p wave and s wave from the media surface reflection, π phase difference between tow images is lead in. The identical section can be canceled out and the different section can be reserved. So the optical image subtraction is achieved. The primary theory is introduced and the proving experiment is carried out in the paper, which certifies the method is easy, utility and effective. |
| Keywords: | optical image subtraction linearly polarized light holography |
