利用光栅对字符进行相加和相减
Optical addition and subtraction of characters by grating
摘要
利用光栅作为滤波器,在相干光处理系统中可对字符进行相加和相减.本文介绍利用正弦光栅和Ronchi光栅对字符进行相加和相减,对这两种情形中相加后的一级象强度进行了比较.
Abstract
The addition and subtraction of characters can be performed in a coherent optical processing system if a grating is used as a filter. In this paper, we describe the addition and subtraction of characters by a sinusodal grating and a Bonchi grating. We compared the intensities of the first order image after addition by sinusoidal grating with that by Eonchi grating.
