ILLUMINATING DEVICE, IMAGING SYSTEM, IMAGING SYSTEM INCLUDING THE ILLUMINATING DEVICE, ENDOSCOPE SYSTEM INCLUDING THE IMAGING SYSTEM, AND MICROSCOPE SYSTEM INCLUDING THE IMAGING SYSTEM
An illuminating device includes an illumination pulse generator configured to generate illumination pulses of coherent light, a speckle modulator configured to modulate speckle caused by the coherent light, and a synchronization controller configured to control the illumination pulse generator and the speckle modulator so as to synchronize pulse generation timing of the illumination pulse generator and drive timing of the speckle modulator. The speckle modulator periodically changes a driving intensity of the speckle modulator.
