    Abstract: An apparatus for controlling an output gain of a silicon photomultiplier device according to the present invention comprises an analog signal processing unit for converting light incident on a silicon photomultiplier device into an analog voltage signal; a digital signal processing unit for receiving the analog voltage signal from the analog signal processing unit and converting the received analog voltage signal into a digital signal; and a control unit for controlling the digital signal processing unit and the silicon photomultiplier device. The control unit receives the digital signal from the digital signal processing unit, and compares the digital signal with a threshold value. When the digital signal exceeds the threshold value, the control unit adjusts the output gain of the silicon photomultiplier device by decreasing a voltage output from the silicon photomultiplier device.

    Abstract:  光モジュールにおいて信号光の受光パワーモニタの校正装置を実装して、受光パワーの測定値を少ないリソースで現実値に高精度かつ高速に校正する。校正装置には信号光の受光パワーの測定値を校正するときに参照されて複数の参照値と複数の現実値との相関関係に基づいて予め複数の校正値を格納した校正テーブルを具備する。校正テーブルでは、参照値の変化に対して現実値の変化が小さい区間では、参照値の変化に対して現実値の変化が大きい区間に比べて、複数の参照値の間隔を小さくして複数の校正値を格納する。信号光の受光パワーの測定値を示す入力値が校正テーブルの参照値と一致する場合、校正装置は参照値に対応付けられている校正値を校正テーブルから読み出す。一方、入力値が校正テーブルの参照値と一致しない場合、校正装置は入力値に基づいて所定の演算式に従って校正値を算出する。

    Abstract: An accurate and rapid method for characterizing the performance of an APD and setting its operating voltage Vop to an optimal value uses an on-board LED or other pulsed light source to measure APD responses at different operating voltages Vop. An estimated breakdown voltage Vb is determined by comparing the measured responses, and the Vop is adjusted to a new value at a fixed offset from the estimated Vb. The fixed offset is selected according to ambient light conditions, including the presence or absence of light background noise, and whether the sun is partially or fully in the field of view. The method is iterated until convergence, or until a maximum number of iterations is reached. In embodiments, a plurality of APD's having a common Vop can be adjusted, and the Vop is never set below a minimum value VopBW necessary to meet timing requirements for a missile guidance system.
