Abstract
PURPOSE:To obtain a drift correction method that the correction of drifts is accurate and the drifts can continually be corrected even when the quantities of the drifts become larger, by using alternating currents, which have no noise and possess arbitrary wave-forms, as integral input. CONSTITUTION:Voltage with positive chopping waves is applied to an electric distortion element from a drive voltage source 10, and photoelectric output a is gained, shaped to gate pulses b through an amplifier 11, a peak detector 20 and a pulse shaping circuit 21 and applied to a gate 13. The drive voltage of the voltage source 10 is converted into alternating signals through a negative direct current bias circuit 22, and applied to the gate circuit 13 as integral input signals. Thus, the integral input signals C are gated by the gate pulses b, and applied to an electric distortion element 23 for correcting drifts through an integrator 14 and an amplifier 23. Consequently, correction is accurate, and drifts can continually be corrected even when the quantities of the drifts become larger.
