Abstract
Disclosed is a light source device capable of further enhancing an effective pulse rate. A light source device according to the present invention comprises: a plurality of light sources (1a to 1h) emitting radiation light; a rotating reflection body (2) having one or more reflection surfaces (2a) and emitting the radiation light emitted from the respective light sources (1a to 1h) along an optical path (L) common to the light sources; a position detecting device (5) detecting a position of the reflection surface (2a) of the rotating reflection body (2); a timing control circuit (6) generating a synchronization signal for driving the plurality of light sources in synchronization with the position of the rotating reflection body based on an output signal from the position detecting device; and a power supply circuit (7) sequentially pulse-driving the light sources based on an output signal from the timing control circuit.
