摘要： A plurality of first cylindrical lenses aligned in an array, having a collecting function with respect to an alignment direction parallel to the array, to collect luminous flux from a body to be imaged. A first reflective collector-surface having a reflective collecting function with respect to a perpendicular direction perpendicular to the alignment direction collects the luminous flux from the plurality of first cylindrical lenses, and provides a collected parallel luminous flux to a plurality of roof-mirror type reflective plane-pairs or to a plurality of right-angle prisms. The plurality of roof-mirror type reflective plane-pairs or right-angle prisms reflects the luminous flux toward a second reflective collector-surface disposed for convergence of the luminous flux with respect to the perpendicular direction. The second reflective collector-surface reflects the luminous flux toward a plurality of second cylindrical lenses disposed for convergence of the luminous flux with respect to the alignment direction. Further, the luminous flux from the plurality of second cylindrical lenses converges to form an image.

摘要： A light source device includes: multiple light source units each including a light source to emit a first color light beam, each of the multiple light source units configured to: convert at least part of the first color light beam into a second color light beam emitted from an emitting region; and emit the second color light beam to form a conjugate image; and a light combiner to combine the conjugate images formed by the multiple light source units to form a combined image, in which the conjugate images partially overlap each other, on a plane of an entrance surface of a light uniformizing element along a central axis of the light uniformizing element. A conditional expression below is satisfied: 1.3>SC/SI>0.7 where SC is an area of the combined image, and SI is an area of the entrance surface of the light uniformizing element.

摘要： A display device, a display system, and a mobile object. The display device includes an image forming unit through which image light exits, an imaging optical system having a reflection plane and configured to form an image by reflecting the image light on the reflection plane, and a housing accommodating the image forming unit and the imaging optical system. The housing has a transmissive area through which the image light reflected by the imaging optical system passes through, and an inclination of the reflection plane is changed to reduce a project area of the reflection plane. The project area is projected to outside of the housing through the transmissive area. The display system includes the display device, and a reflector configured to reflect the image light reflected by the imaging optical system. The mobile object includes the display system, and the reflector is a front windshield.

摘要： A display device includes a screen to form an intermediate image with light; a concave mirror, and a first mirror disposed between the screen and the concave mirror. The first mirror includes a first reflective area to reflect the light emitted from the screen to the concave mirror; a second reflective area to reflect the light emitted from the concave mirror to an area where a virtual image is formed; and a common reflective area in which the first reflective area and the second reflective area at least partly overlap on each other.

摘要： A light source device comprising: a light source section which generates any one of blue light, red light, and green light; a phosphor which generates a fluorescence including the two colors other than the color of the light emitted from the light source section; a color-changing section which changes one of the two colors of the fluorescence emitted from the phosphor to another color regularly and irradiates it to the image-forming element; and a light path-switching section which switches a light path in which a fluorescence excited by the color light emitted from the light source section passes towards the color-changing section and a light path in which the color light emitted from the light source section passes towards the image-forming element regularly.

摘要： An information display apparatus emits an image forming light beam to a transmissive reflection member and makes a virtual image visible through the reflection member. The information display apparatus is configured to display the virtual image so that a difference between a convergence angle when viewing the virtual image through the reflection member and a convergence angle when viewing a real object through the reflection member is less than or equal to 1 degree.
