Abstract
The sensitivity of electro-optical Earth surveillance systems within visual and near-IR bands is provided with the charge accumulation process in CCD matrices as image receivers. Efficiency of that process is affected by irregular image movement caused mostly by linear and angular fluctuations of an airplane or a space vehicle on the flight trajectory. Optical image stabilization systems under consideration compensate the movement and allow it to meet signal-to-noise requirement without space resolution degradation. Two constituents of the image stabilization system are measurement subsystem and compensation subsystem. Analog- digital compensation subsystems were investigated, the main compensation errors being estimated. In this report similar consideration of measurement subsystems is presented.
