摘要:	本論文將C4M-OS(C for Microcontroller Library)應用於過去開發的創新恒定光子計數控制式暉光儀，並將電路製作成能與ASA_M128的v3板相容的光子恒定式光度計介面卡。C4M-OS為以C語言撰寫微控制器應用軟體之創新作業系統，利用此一作業系統能週期性收取資料、使開發更加容易的優點，來完成擁有高靈敏度的光子恒定式光度計。執行上可以依照傳統的正比光子數方式量測微光，或者使用光子數恒定控制來量測微光。也能夠選擇只需單筆量測或是選擇週期性連續量測。光子恒定控制是利用當光子數被控制到維持固定時，高壓電數值會與光強度成反比的特性，當儀器接收到強光的時候，以前饋控制方式調整高壓電電源使光電倍增管輸出的光子數達到恒定控制，以達成高精度高量測範圍之光強度量測。在實驗設計部分將沿用有10倍光學衰減器的校正平台來模擬兩種相差10倍光強度的光，用以測試本光子恒定式光度計的可行性。 ;In this research, C4M-OS (C for Microcontroller Operating System) is applied to the innovative Constant Photon Count Control (CPCC) airglow instrument developed in the past, and the circuit is made into a photon constant photometer interface card compatible with the v3 board of ASA_M128. C4M-OS is an innovative operating system for writing microcontroller application software in C language. This operating system can periodically collect data and let development become easy. By the operating system, we can complete a photon constant photometer with high sensitivity. In implementation, it can measure the low light according to the traditional proportional photon number method, or use the constant photon number control to measure the low light. It is also possible to select only a single measurement or periodic continuous measurement. Photon constant control uses the characteristic that when the number of photons is controlled to remain fixed, the high voltage value will be inversely proportional to the light intensity. When the instrument receives strong light, the feedforward control method adjusts the high voltage power supply to the photomultiplier tube. The number of output photons can be controlled to achieve constant control, achieving high-precision and high-measurement range of light intensity measurement. In the experimental design part, a calibration platform with a 10-fold optical attenuator will be used to simulate two kinds of light with a difference of 10 times the light intensity to test the feasibility of the photon constant photometer.
