This paper designs a total of 250mm dual-channel optical system
including visible (0.5m0.8m)
infrared (3m5m). The main system is a three-reflection system
and the primary mirror is designed as the first and the third reflecting surface with different figuring. The cooling infrared detector was choiced in infrared channel and achieves 100% cool shield efficiency of luminescence through the second imaging. The main benefits of this design are the large corrected and unvignetted FOV
an easily baffling of stray light
small encumbrance and an easy handing. 2011 IEEE.

Narcissus can have a deleterious effect on image quality for cooled infrared imaging systems. 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.
