摘要In order to increase the illumination uniformity of the position-sensitive detector (PSD) in a sensing optical system, an optimization method is introduced in this paper. The ratio of the oblique ray section to the paraxial ray section is adjusted by circular and annular obscurations with different parameters; thus, the relative illumination on the image plane can be optimized. In our case, the size and position of the circular and annular obscurations are optimization variables. The result shows illumination uniformity on a PSD is enhanced from the original 12%-69.7%, and the precision is greatly improved. The method in this paper is proved to be effective and low cost and to have potential in many other applications. (c) 2012 Optical Society of America
