Abstract

PURPOSE:To avoid uneven sensitivity, by injecting the reference infrared rays to an infrared detector and changing the bias current of each detector through the use of output of the detector. CONSTITUTION:A revolution signal is given from a sensitivity correction multiplexer 9 to a motor 10, and a rotary plate 12 is turned. A blade synchronism signal 13 is given to the multiplexer 9 from the motor 10. The multiplexer 9 detects the difference of the sensitivity between the detectors based on the output of the amplifier 6 provided each detector of the infrared detector train 2 and the signal 13. The multiplexer 9 gives a bias current 14 to each detector based on the difference of sensitivity. Thus, the sensitivity of each detector is equalized by giving the bias current.
