| Abstract: | Discusses the design of the cold light illuminator and the design of lens used in grating projection. These two comprise grating projective system. The former uses the infrared transmitted cold mirror which has high reflection in visible wavelength and more than 80 % transmission in infrared wavelength. In this way, the sendout light produces low heat effect and the error in measurement is decreased. The later uses the basic symmetry structure, and the spherical aberration and distortion have been corrected, so the image quality of the grating has been obviously improved. |
