Paper Abstract

In this paper, two new techniques are proposed for manipulation of the microsatellite imaging structures and sensors in order to reduce the micro-satellite’s weight and improve the image quality. Theses satellites generally include three mirrors. First, replacing primary mirror by deformable mirror with appropriate actuators is suggested. In this design, the primary mirror is replaced with deformable mirror (DM) and the secondary mirror can be aligned in the cassegrain design and tertiary mirror could be ignored. Second, by changing the position of sensor, the image quality of different pixels could be changed. Normally, when the sensor is fixed, parts of the image might be blurred, noisy and distorted. Therefore, if the sensor is capable of changing its position, the quality of the distorted pixels will be improved but other parts will become blurred. In this case blurred pixels should be omitted and improved pixels should be saved and final image would be taken form processed pixels. In this paper a new concept of “local focusing” is introduced. This concept aims to process images at a variable distance of a sensor, which can cause the final image quality to become better than the fixed sensor.
