Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 実効パルスレートを一層高くすることができ る光源装置を提供する。 【解決手段】 本発明による光源装置は、放射光を放出 する複数の光源(1a〜1h)と、1個又はそれ以上の 反射面(2a)を有し、各光源(1a〜1h)から放出 された放射光を前記光源の共通の光路(L)に沿って出 射させる回転反射体(2)と、この回転反射体(2)の 反射面(2a)の位置を検出する位置検出装置(5) と、位置検出装置からの出力信号に基き、前記複数の光 源を回転反射体の位置に同期して駆動させるための同期 信号を発生するタイミング制御回路(6)と、タイミン グ制御回路からの出力信号に基づき、前記光源を順次パ ルス駆動させる電源回路(7)とを具えることを特徴と する (57) [Summary] To provide a light source device capable of further increasing an effective pulse rate. SOLUTION: The light source device according to the present invention has a plurality of light sources (1a to 1h) for emitting radiation light and one or more reflecting surfaces (2a), and emits light from each of the light sources (1a to 1h). A rotating reflector (2) for emitting the emitted radiation along a common optical path (L) of the light source, and a position detecting device (5) for detecting the position of the reflecting surface (2a) of the rotating reflector (2). ) A timing control circuit (6) for generating a synchronization signal for driving the plurality of light sources in synchronization with the position of the rotary reflector based on an output signal from the position detection device; and an output signal from the timing control circuit. And a power supply circuit (7) for sequentially driving the light source in pulses.
