| Summary: | 碩士 === 國立中央大學 === 光機電工程研究所 === 105 === In order to measure the airglow in the ionosphere, our laboratory developed a photo-tomograph instrument . The instrument, taking micro-controller as control unit, count the pulse from photomultiplier tube. During calibrating the photomultiplier tube, it is found that the original circuit design of the photo-tomograph instrument restricts the measurement range. To resolve the restriction , two approachs are conduct to improve the original design.
A new design of the photo-tomograph instrument, and its reintegrated calibration platform of photomultiplier tube are accomplished. Result show that the measurement intensity range can be expended by the adaptive control together, with change to the photomultiplier supply voltage .
