Digital Sensors and Sensor Sysstems


Abstract: The target object must stay in the permanent position within telescopic field of vision during the long-playing exposure of astronomical photograph; otherwise it may blur the picture. For this reason, the telescope has to track the target objects precisely in a long time. So the function of guiding star is necessary: Due to the level of accuracy of the equipment or the Polar axis, the telescope sometimes fail to track the target object precisely during the long time tracking process while the guiding star helps to adjust the telescope through monitoring the movement of the target object so that it remains a certain position within the field of vision. But the function of guiding star above is based on PC equipment which is very expensive, heavy and high power consumption. So a new study is to design a cheap, high-performance and portable embedded guide-star system to discard the previous operating system which is expensive and difficult to operate which has to run on a PC on which is installed the specific guiding star CCD.


Keywords: Guide star, Embedded system, Track star, Portable.
