| 英文摘要 | PURPOSE:To set an optical output by a semiconductor laser so as to be faithful to image information and also, to obtain a state that an output fluctuation is corrected by selecting one of driving current setting parts provided by plural stages in accordance with the input of a signal. CONSTITUTION:The title controller is constituted of a driving current setting part provided with plural switches 2, 3 for operating plural constant-current sources, and correcting parts C, C for correcting an output fluctuation caused by thermal coupling of a semiconductor laser for emitting a light beam by a driving current in this setting part. In this state, in accordance with the input of a signal, one of those plural driving current setting parts is selected. In such a way, an image can be reproduced faithfully in accordance with the state of an image to be reproduced, and also, an output fluctuation by the semiconductor at the time of its reproduction can be corrected. |
