Paper Abstract

A photoelectric autocollimator employing an area Charge Coupled Device (CCD) as its target receiver, which is specially used in numerical stage calibration is optimized, and the various error factors are analyzed. By using the ZEMAX software, the image qualities are optimized to ensure the spherical and coma aberrations of the collimating system are less than 0.27mm and 0.035mm respectively; the Root Mean Square (RMS) radius is close to 6.45 microns, which is identified with the resolution of the CCD, and the Modulation Transfer Function (MTF) is greater than 0.3 in the full field of view, 0.5 in the centre field at the corresponding frequency. The errors origin mainly from fabrication and alignment, which are all about 0.4" . The error synthesis shows that the instrument can meet the demands of the design accuracy, which is also consistent with the experiment.
