摘要： A projection device including an imaging module, a freeform-surface reflective mirror, and a projection lens assembly is provided. The imaging module is configured to provide imaging beams and includes a display panel and a light-source module. The imaging beams are transmitted toward the projection lens assembly by the freeform-surface reflective mirror. The projection lens assembly includes a first optical axis and a second optical axis. The first optical axis passes through the projection lens assembly. The imaging beams emitted by the projection device form an imaging-beam region, in which the first optical axis does not pass through a geometric center of the imaging-beam region, and the second optical axis passes through a geometric center region of the display panel. The geometric center region is a region having a distance less than or equal to 40% of a minimum width of the display panel from a geometric center of the display panel.

摘要： A doubly curved reflector for compact storage in a folded state includes a plurality of gores, each gore having on either long side a gore side curve. At least one hinge is mechanically coupled between each adjacent gore, the at least one hinge including a fold roll hinge or a living hinge. In a stowed doubly curved reflector state each gore folds about the at least one hinge when folded closed such that a face surface of each gore folds against an adjacent face surface of another gore into a substantially cylindrical structure. In a deployed doubly curved reflector state, each hinge. A doubly curved reflector for compact storage in a folded state and a locked open state, a method of manufacture, and a method for designing a substantially wrinkle free doubly curved foldable reflector having gores of a composite material are also described.

摘要： A head-mounted display according to the present embodiment includes a combiner which is aspherical, arranged in front of a user, and configured to reflect display light for forming a display image toward the user, and a beam splitter which is arranged between the combiner and the user, and configured to reflect the display light to the combiner and transmit display light reflected by the concave mirror. In an optical system, in a range outside the effective viewing angle, the distortion exceeds 5% and increases toward an outside of a viewing field.

摘要： The information display apparatus configured to display video information of a virtual image on a reflecting surface of conveyance includes: a display configured to display the video information; and a virtual image optical system configured to display a virtual image at a front of the conveyance by reflecting light emitted from the display by means of the reflecting surface. The virtual image optical system includes a concave mirror and an optical element. The optical element is arranged between the display and the concave mirror, and is configured to correct distortion of the virtual image obtained so as to correspond to a viewpoint position of a driver on a basis of a shape of the concave mirror and a shape of the optical element. The information display apparatus further includes a virtual image double image conversion reducer configured to reduce double image conversion of the virtual image.

摘要： A head up display (HUD) with improved resistance to sunload for use in a vehicle comprising an image generating device, an LCD assembly, an optical bonding assembly, and a fold mirror, with specific design countermeasures to combat damage caused to an LCD by heat from sunlight. These include an OB glass and cold mirror film (CMF) as components of the optical bonding assembly, a hot mirror coating and a polarized film as components of the LCD assembly, and a cold mirror coating on the fold mirror. When sunlight enters the HUD, the cold mirror coating reflects only visible light towards the LCD. The hot mirror coating reflects infrared and ultraviolet wavelengths of light away from the LCD. The polarized film cuts p-polarized light. The OB glass and CMF increase the specific heat of the HUD. The HUD thereby reduces sunload that would otherwise damage the LCD due to heat stress.

摘要： A laser sensor system including a common optical bench that is configured to receive and process different beams of a high energy laser (HEL). The common optical bench is configured to handle the different beams using a modular set of optical components. Optical components of the common optical bench include a filtering device configured to reduce the power of the beams, a common collecting optical element that is configured to set an imaging position and focal length for the beams, a position sensitive detector (PSD) arrangement that is configured to measure angular and positional errors in the beams, and various compaction optical elements, such as mirrors, that are configured to enable compaction of the laser sensor system by increasing the focal length of the beams.

摘要： A reflection plate includes a substrate, an insulation film disposed on the substrate and including projection portions and recesses on an uneven surface, and a reflection film disposed on the uneven surface and having a surface that conforms to the uneven surface and reflecting light. The projection portions are arranged at intervals and are inclined with respect to a normal direction of a surface of the substrate. The recesses are between the projection portions that are adjacent to each other. The projection portions include a first projection portion, a second projection portion, and a third projection portion that are inclined in different directions.
