摘要： Provided are a bezel body and a vehicular display device that effectively reduces a sense of discomfort provided to a passenger by making reflection on a windshield less visible. Since a reflection portion is formed in a predetermined area on a lower surface of a light guide member at the rear side, the guided external light is easy to reflect upward, whereby light can efficiently be emitted from the light guide member toward a descending wall. Therefore, this configuration can prevent the descending wall from being darkly reflected on a windshield, thereby making the reflection less visible and effectively reducing a sense of discomfort provided to the passenger.

摘要： Devices, systems, and methods for glare reduction in surgical microscopy are provided. A method of operating a surgical microscope may include: receiving light reflected from the surgical field at an image sensor; processing the received light to generate image data; identifying portions of the image data representative of glare; and controlling an optical element to limit the transmission of light associated with the glare. A surgical microscope may include: an image sensor configured to receive light reflected from the surgical field, a computing device, and an optical element. The computing device may be configured to: identify portions of the light received at the image sensor associated with glare and generate a control signal to limit the transmission of the light associated with the glare. The optical element may be configured to selectively limit the transmission of the light associated with the glare in response to the control signal.

摘要： A near-eye optical display system utilizes a compact display engine that couples image light from an imager to a waveguide-based display having diffractive optical elements (DOEs) that provide exit pupil expansion in two directions. The display engine comprises a pair of single axis MEMS (Micro Electro Mechanical System) scanners that are configured to reflect the image light through horizontal and vertical scan axes of the display system's field of view (FOV) using raster scanning. The MEMS scanners are arranged with their axes of rotation at substantially right angles to each other and operate with respective quarter wave retarder plates and a polarizing beam splitter (PBS) to couple the image light into an in-coupling DOE in the waveguide display without the need for additional optical elements such as lenses or relay systems.

摘要： A head-mounted display includes an image forming part, a half mirror reflecting a part of an image light emitted by the image forming part toward an optical pupil position, and a wall part. Given that an intersection point between the half mirror and an optical axis of the image light is defined as a first intersection point, an intersection point between the wall part and the optical axis is defined as a second intersection point, a distance between the first intersection point and the second intersection point is defined as a first distance, and an angle at which the wall part inclines with respect to the optical axis is defined as a first angle, the first angle and the first distance are set such that the image light passed through the half mirror and reflected by the wall part reaches a position different from an optical pupil position.
