| Abstract: | The Space target scene simulator（STSS） is the key device for evaluating and calibrating the ability of detecting star magnitude of optical detectors.In consideration of STSS needing to evaluate and calibrate 16m magnitude,a single photon counters based on photomultiplier is designed as a simulated star magnitude energy detector.The method for selecting photomultiplier and the design principle of potential divider are brought forward in this paper.Finally,It is proved that the simulated star magnitude energy detector has the enough ability to evaluate and calibrate the simulated magnitudes by an experiment,which is implemented to measure the accuracy of single photon counter. |
