Abstract

Optic imaging system is information transmission system. The quality of imaging depends on the transmission characteristics of optical system completely. The bi-grating diffraction imaging is the formation of the image of an object with two gratings. First,gather object information and transform them into object beams by irradiatiion of incandescent lamp. Then the first grating disperses the muti-color object beams with object information and second combines the dispersed light beams to form the image.This paper describes the characteristics of information about object color and size transmission. The characteristic is studied by theoretical analysis. The relationship between the two gratings' spatial frequencies and diffraction orders that reflecting the information of object color and size transmission quality on certain condition is given. To recognize the transmission characteristics of bi-grating diffraction imaging deeply is very helpful for its application.
