Abstract:
1. A light source device comprising: a first light source configured to emit a first source light in a first wavelength range; a source light modulator comprising a first face, a second face through which the first source light enters the source light modulator, a first area, and a second area, wherein the first area is configured to have the first source light having entered through the second face pass therethrough, and to output a transmitted light from the first face, and wherein the second area comprises a phosphor layer and is configured to reflect a reflected light excited by fluorescence excitation in a wavelength different from the first wavelength range by being irradiated by the first source light having entered through the second face, and to output the reflected light from the second face; a second light source configured to emit a second source light in a second wavelength range that is different from the first wavelength range; an integrator configured to uniformalize luminescence distribution of light input through a light incidence face thereof; and a light guiding optical system configured to guide the transmitted light, the reflected light, and the second source light to the light incidence face of the integrator, wherein the light guiding optical system comprises:
