| description | To provide a master device capable of supplying salve devices with timing data that enables the slave devices to operate stably.SOLUTION: The master device includes: an amplitude control unit that controls the scan amplitude of an MEMS mirror that scans laser light emitted by a light-emitting unit; a generation unit that generates TM data, on the basis of the operation of the MEMS mirror, which represents a timing at which the scan angle of the MEMS mirror becomes zero; a buffer that stores TM data in one frame of scan of the MEMS mirror; a light emission control unit that controls emission of laser light by the light-emitting unit, on the basis of generated TM data; and an output unit that outputs data to slave devices. When the scan amplitude of laser light by the MEMS mirror is changed, the light emission control unit controls light emission using one frame of TM data stored in the buffer, in place of generated TM data, and the output unit outputs one frame of TM data stored in the buffer to the slave devices.SELECTED DRAWING: Figure 14
【課題】スレーブ装置を安定的に動作させるタイミングデータをスレーブ装置に供給可能なマスタ装置を提供する。【解決手段】マスタ装置は、発光部によって発光されるレーザ光を走査するＭＥＭＳミラーの走査振幅を制御する振幅制御部と、ＭＥＭＳミラーの動作に基づきＭＥＭＳミラーの走査角度がゼロになるタイミングを表すＴＭデータを生成する生成部と、ＭＥＭＳミラーの走査の１フレームにおけるＴＭデータを記憶するバッファと、生成されるＴＭデータに基づいて発光部によるレーザ光の発光制御を行う発光制御部と、スレーブ装置にデータを出力する出力部とを含み、ＭＥＭＳミラーでのレーザ光の走査振幅が変更されるときに、発光制御部は、生成されるＴＭデータの代わりにバッファに記憶された１フレームのＴＭデータを用いて発光制御を行うとともに、出力部は、バッファに記憶された１フレームのＴＭデータをスレーブ装置に出力する。【選択図】図１４ |
