Abstract: Described is herein a radiation measuring apparatus in which a detected pulse signal having a wave height value proportional to energy of radiation is transmitted through an optical fiber and a detected pulse signal received from the optical fiber is supplied to an external apparatus. Even if the transmission loss of the optical fiber is subjected to change with passage of time, a monitor pulse signal having a polarity reverse to that of a detected pulse signal is overlapped on the detected pulse signal lest the wave height of the detected pulse signal be not varied on the transmitting side, and a wave height value of a monitor pulse signal passed through the optical fiber is detected to compensate the wave height of the received detected pulse signal using the detected value.

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: The objective of the present invention is to quickly and precisely correct the measured value for light reception power to the actual value with few resources, by installing a correction device for a light reception power monitor for signal light in an optical module. The correction device is equipped with a correction table which is referenced when correcting the measured value for the light reception power of signal light, and in this correction table multiple correction values are stored in advance on the basis of the correspondence relationships between multiple reference values and multiple actual values. In the correction table, for segments wherein the change in the actual values with respect to the change in the measured values is small, the interval between the reference values is made smaller and more correction values are stored than for segments wherein the change in the actual values with respect to the change in the measured values is large. When an input value indicating the measured value for the light reception power of the signal light matches a reference value in the correction table, the correction device reads from the correction table the correction value corresponding to the reference value. When an input value does not match a reference value in the correction table, the correction device calculates a correction value in accordance with a prescribed calculation formula on the basis of the input value.
