| 摘要 |
An optical source device includes a solid high frequency oscillating unit that outputs a high frequency signal, a waveguide that receives the high frequency signal output from the solid high frequency oscillating unit and radiates the received high frequency signal as a microwave, and a light emitting unit that emits light by the microwave radiated from the waveguide unit. A container of the waveguide unit has a space surrounded by reflective surfaces that reflect the microwave radiated from the antenna unit so as to collect the microwave. A projector includes this optical source device, an optical modulating unit that modulates a light beam emitted from the light emitting unit of the optical source device according to image information to form an optical image, and a projecting unit that projects the optical image formed by the optical modulating unit.
