In this paper, the problems of illumination stage and illumination window which can meet the target space aerocraft illumination conditions are analyzed particularly in the two aspects: natural and abnormal space interconnection.

Reservoir algorithm is used to sample from these single data stream respectively,then some multiple snapshot windows are constructed,the relationship between these single data stream and multiple snapshot windows is bijective mapping,the relationshi.

Selection of droplet transfer specific spectrum window;

Thermo-optical sensitivity and thermal control system for manned spaceship optical windows;

A cryostat with optical windows designed for fabricating the ICF cryogenics target;

In the aero-dynamic environment, optical window s shape and optical property will be changed because of thermal transmission and thermal stress, then the transmission of the infrared radiation from the target will be affected, which will make the image fuzzy, flutter, departure and energy s attenuation, thus, the effectiveness of infrared image will be heavily affected.

In this paper,thermal stress and phase change induced by temperature rise of laser window are analyzed.
