In order to ensure appropriate exposure time
and no exposure while electric charge is transferring after taking a photograph
it is necessary to have the shutter mechanism cooperate with CCD for area CCD aerial cameras. The ground object illumination has a wide range which is from 4000Lx to 100000Lx
so a shutter which is high efficient and a continuous stepless adjustment are also required. This paper introduces the fundamental principle
structural design and control procedure about this new focal plane shutter. Under the control of DSP
the velocity of shutter curtain governed by the shutter motor can be not only precisely controlled
but also the durability and the reliability are increased. The experiment results have shown that this new shutter has the higher stability of movement
long life span with more than 105 operating times
a wide range of exposure time from1/ 50s to 1/ 320s(depending on the slit width)and the exposure error is less than 10%. With the CCD gain adjustment
the performance of this shutter is fully satisfied with the requirements of area CCD aerial cameras. 2010 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.
