Optical System Design Of The Detection Of Checking Target Lens

The article describes the target mirror calibration device is consists of the Zoom of Collimator, CCD camera system, image interpretation system. The article discussed also around the two parts of the optical system design.To simulate the different distance to target of target mirror,in this paper,application of mechanical compensation to designed zoom collimator,as follows of the specific technical parameter:M=2:1, in500-1000mm of range within can achieved zoom, for f=500mm, and600mm, and750mm, and1000mm four a focal length on its for found, image high y=5mm, D/f=1/10, visible light, as frequency for80pl/mm. View of the longer the focal length of the system, and correction of secondary spectrum is particularly critical micro-structure of anomalous dispersion glass and through complicates the structure of two groups successful correction of secondary spectrum; zoom with mechanical compensation method produces the image to move, get zoom curves gently, uniform collimator focal power distribution system. after with high precision2million pixels CCD image system receives, specific technology parameter are as follows:NA=0.05, y=5mm, system of dispersion spots diameter≤0.03～0.1mm, distortion in2～4%, CCD image system pixels size1/1.8inch, like Yuan number1628(H)×1236(V), Pixel size5.4μm×5.2μm, level drive frequency for36MHZ, output frame rate for15frame/s. as frequency for80pl/mm. The relay system structure selection in the form of two pieces of two pieces of double agglutination of symmetric lens.through the optimization of optical software Zemax.got the good imaging quality of relay system with CCD as image receiving device.Finally got a complete set of high accuracy detection device of target lens system.
