Abstract:
A multi-element sensor calibration apparatus comprising:a light reception unit for receiving incident light to convert the received incident light into an electric signal;a calibration signal output unit for outputting a calibration signal used to calibrate said electric signal;a transfer unit for transferring said electric signal and said calibration signal, said transfer unit extending substantially the full length of said light reception unit;a gate for executing a gating operation of said electric signal in such a manner that when said gate is set to an ON state, said electric signal derived from said light reception unit is outputted to said transfer unit whereas when said gate is set to an OFF state, outputting of said electric signal to said transfer unit is interrupted;a calibration signal output control unit for performing output control of said calibration signal in such a way that when said gate is set to the ON state, said calibration signal is not outputted to said transfer unit, whereas when said gate is set to the OFF state, said calibration signal is outputted to said transfer unit; andan adjustment unit for adjusting a level of said calibration signal provided between said transferring and said calibration signal output control unit.
