Abstract:
1. A light source device comprising: a first light source configured to emit light in a first wavelength band; a light-source light generation section configured to generate light-source light of each of a plurality of colors by time division by using light-emission of the first light source; a second light source configured to generate light-source light of a second wavelength band different from the first wavelength band; and a light source control section configured to cause each of the light-source light generation section and the second light source to generate light-source light in one period, and to control a drive timing of each of the first and second light sources to adjust a light-emission timing of light-source light generated by each of the light-source light generation section and the second light source, wherein: the first light source emits laser light of a blue wavelength band, and the light-source light generation section is a color wheel formed by providing at least a fluorescent substance layer for generating light of a green wavelength band by using the laser light as excitation light, and a diffusion layer for diffusing/transmitting the laser light, in a juxtaposing manner in a circumferential direction of the color wheel.
