| 英文摘要 | PURPOSE:To faithfully reproduce a picture in corresponding to a modulation signal by delaying the impression completing time of a driving current after correction in corresponding to a delaying time corresponding to a correcting quantity. CONSTITUTION:A correcting means 11 is constituted of a phase correcting circuit 11A connected to a semiconductor laser driving circuit 2 and a differentiation circuit 11B and the phase correcting circuit 11A adjusts the timing of performing correction to the light emission of a semiconductor laser 1 by inputting a modulation signal to the circuit 2 as a phase-delayed signal after the modulation signal is delayed on a delay line 11a. Therefore, the impression of a corrected driving current is continued until the leading time corresponding to the delayed operation starting time of the semiconductor laser Accordingly, the operating time of the laser 1 is made to correspond to the impressing time of the modulation signal and the reproduction of a picture by means of the modulation signal can be performed faithfully. |
