This paper demonstrates the effects on photoelectric detection system bring out by stray light. On this foundation  build up evaluation index of stray light system  to search the reasonable programme to eliminating stray light. A detailed telescope system geometry model was created  and scatter models were create for telescope and enclosure components. By the means of designing the structure of main baffle  baffle vane and the coating technology. In order to verify the prosperity of structure that designed  we utilizes software to analysis opto-mechanical model. we utilizes software to analysis opto-mechanical model. The simulations show that point source transmittance of the system is thus reduced by up to two orders of magnitude between 10-8 and 10-10. Meanwhile  the experiment obtains clean detection data which satisfies the system requirements. Stray light has been suppressed effectually  and so measurement precision was improved from detection graphics.

Therefore  analysis of narcissus is important for designing both scanning and staring optics. Narcissus is generally assumed to be negligible in staring IR optical designs because the shading effects can be removed by calibration of the detector array data. However  the calibration usually decreases sensitiveness of the system and Narcissus variation may be noticeable for sensors when the conditions changes as follows: 1. warming and cooling the optical housing  2. zooming optical elements  3. movement of lenses for focus. In that case  it will result in shading and other image defects even after calibration. To minimize these effects  narcissus should be assessed and controlled during the design of staring array IR system. We provided a direct and fast method for analyzing the narcissus variation in the presence of software such as LightTools  TracePro and ASAP  and proposed the principles in optical design of staring IR systems to reduce narcissus. A cooled staring IR system with serious narcissus was estimated and reoptimized. Narcissus analysis of this IR system confirmed the efficiency of the analysis method.
