Title: Light reception circuit
Inventor: NISHIMOTO HIROSHI
IPC: H04B10/07
Filed: 1987-07-17
Abstract: PURPOSE:To always operate an APD with the value of an optimum current gain M by separating the APD from an AGC control type and providing an APD bias voltage correcting resistance. CONSTITUTION:A bias voltage VAPD of an APD bias voltage control circuit 5 follows the characteristic change of an APD 1 and is operated so as to eliminate the temperature change of a current gain M. On the other hand, the optimum current M to make the S/N of an APD maximum has a characteristic that it is reduced little by little to the increase in an optical input level. Since the voltage control circuit 5 is not included in an AGC control system, the bias voltage VAPD outputted is not related to the change of the optical input level. For that reason, when an APD bias voltage correcting resistance R6 is absent, a flat M characteristic is given, and when the R6 is provided, the M characteristic is inclined downward in the right direction, a resistance value is suitably set and thus, the M characteristic can be optimumly approximate to the M characteristic.

IPC: G02B6/00
Filed: 1982-10-13
Abstract: PURPOSE:To reduce the error, by making the light having a specific wavelength incident to an optical fiber used for energy transmission to compensate automatically the measurement error due to the change of the transmission loss when the radiant temperature energy from a measurement object is measured. CONSTITUTION:Since the quantity of light generated from a light source 10 is attenuated by the transmission loss of an optical fiber 2 and the resultant quantity of light is detected by a detector 15, the output of the detector 15 is always measured to detect the variation of the transmission loss of the optical fiber. For the purpose of compensating the measurement error due to this variation the output of the detector 15 is inputted to an operating circuit 16, and an output voltage vf of the detector 15 is divided by a reference voltage Vo to attain a transmission loss value Vf/Vo of the optical fiber, and an output Vt of the detector 15 is divided in an electric circuit 9 by said transmission loss value. As the result, temperature measurement is performed without the influence of the variation of the transmission loss of the optical fiber 2.
