Abstract:
A light source device comprising:a plurality of light sources arranged on a circumference at substantially equal intervals; a rotating reflection body arranged on the center of the circumference and having a reflection surface for reflecting the light emitted from the respective light sources; a driving device for driving the rotating reflection body; a position detection device for detecting an angular position of the reflection surface of the rotating reflection body; a timing control circuit for generating synchronization signals for driving the plurality of light sources in synchronization with the position of the reflection surface of the rotating reflection body based on an output signal from the position detecting device; and a power supply circuit for sequentially energizing the light sources based on an output signal from the timing control circuit; wherein light pulses emitted from the respective light sources are sequentially reflected along an optical axis transversely of a surface including said circumference by way of the reflection surface of the rotating reflection body, the rotating reflection body is arranged on the center of the circumference so as to be enclosed by the plurality of the light sources, and the rotating reflection body comprises a monogon mirror having a single rotating reflection surface.
