Abstract: Abstract:The characteristic of the stray light is analyzed. An improved baffle with four angled vanes is given. The configuration of the baffle is simple and its weight is light. The TracePro software is used to analyze the lightshielding ability. The PST curve is analyzed. The stray light distribution on the detector when the sun is at 30 degree is given to illuminate the straylight uniformity. The results of straylight experiment are given and the curves of the average intensity on the detector’s three regions are analyzed. The simulated result and the experimental result show that the lightshielding ability of the improved baffle is good and can meet the lightshielding requirement of the star sensor.
