  • Patent number: 9599316
    Abstract: A light source device has a first monochromatic light source group, a second monochromatic light source group, a polarization selection and wavelength selection element, a first phosphor layer, and a second phosphor layer. The first monochromatic light source group outputs first polarized light having a fixed polarization direction. The second monochromatic light source group outputs second polarized light having a fixed polarization direction. The first phosphor layer emits light in a first wavelength band. The second phosphor layer emits light in a second wavelength band. The polarization and wavelength selection element directs the first polarized light onto the first phosphor layer by transmitting the first polarized light and directs the second polarized light onto the second phosphor layer by reflecting the second polarized light, reflects the light in the first wavelength band and transmits the light in the second wavelength band.

The condensing optical system is configured so that when a light beam parallel to an optical axis of the condensing optical system is incident on the condensing optical system, the light beam is concentrated at a position on the axis on the incident surface. The parallel light beams are incident at different positions of the condensing optical system while approaching the axis. Emitting positions of the light beams on the condensing optical system and incident positions of the light beams on the incident surface are opposite each other with respect to the axis.

  • Publication number: 20160116304
    Abstract: The purpose of the present invention is to detect the absolute rotation angle of a rotor in a simple manner. In order to detect the rotation angle of a rotor of a stepping motor including a rotor and a stator winding, a first magnetic sensor (151) having a resolution of 200 steps per mechanical angle of 360 degrees detects the rotation angle of a rotor. An incremental encoder (60) outputs a plurality of types of signals periodically in accordance with the rotation angle of the rotor. A rotation angle acquirer (122) in a controller (102) acquires the absolute rotation angle of the rotor on the basis of the rotor rotation angle detected by the first magnetic sensor (151) and the type of signal output by the incremental encoder (60).

    Abstract: A light source device includes a plurality of light sources with different polarizations. A combined wavelength band of the light of a first polarization and second polarization is a first wavelength band. A combined wavelength band of a third polarization and fourth polarization is a second wavelength band. A plurality of selective transmission elements transmits one or more combined light of one or more polarizations and reflects one or more light of one or more polarizations. Thus, the light of the first polarization, the light of the second polarization and the light of the third polarization passing through a third selective transmission element, and the light of the fourth polarization reflected by the third selective transmission element proceed in the same direction.
