Title: Light power measuring instrument
Inventor: OKAMOTO AKIRA
IPC: G01J1/42
Filed: 1986-12-19
Abstract: PURPOSE:To measure accurate light power without being affected by variation of a dark current by providing a photodetecting element, a temperature sensor, a temperature detecting means, a correcting dark current generating means, a current adding circuit, and a photocurrent detecting circuit. CONSTITUTION:The photodetecting element 1 converts input light power into a current and outputs the current. Further, the temperature detecting means 3 is constituted by adding the temperature sensor 2 to the photodetecting means 3,and the sensor 2 detects variation in ambient temperature and outputs a corresponding signal. The correcting dark current generating means 4, on the other hand, outputs a current equal in value to the dark current of the photodetecting element 1 with the output signal of the temperature detecting means 3. Then, the current adding circuit 5 adds the output of the dark current generating means 4 to the output of the photodetecting element 1 to cancel only the dark current in the output of the photodetecting element 1, thereby outputting a photocurrent. The output current of this circuit 5 is detected by the current detecting circuit 6. Thus, only the photocurrent is detected at all times even if the ambient temperature varies.
