摘要： A method and apparatus for capturing an image of at least one object appearing in a wide-angle field of view (FOV). A housing has an image sensor and a lens assembly fixedly mounted relative thereto. The lens assembly includes first and second lens groups, and a glass lens. The lens assembly and the image sensor are aligned such that light received within the FOV passes through a front aperture and the base lens assembly and impinges onto the image sensor. The light received from the FOV forms an original image prior to entering the front aperture and the lens assembly. Light from the FOV impinging onto the sensor forms an impinging image.

摘要： A multipass scanner usable e.g. in a near-eye display is disclosed. The multipass scanner scans a light beam angularly, forming an image in angular domain. The multipass scanner includes a light source, a tiltable reflector, and a multipass coupler that couples light emitted by the light source to the tiltable reflector, receives the reflected light and couples it back to the tiltable reflector to double the scanning angle. Then, the multipass coupler couples the light reflected at least twice from the tiltable reflector to an exit pupil of the scanner. A pupil-replicating waveguide disposed at the exit pupil of the scanner extends the image in angular domain. Multiple reflections of the light beam from the tiltable reflector enable one to increase the angular scanning range and associated field of view of the display without having to increase the angular scanning range of the tiltable reflector.

摘要： A light source optical system used with an excitation light source configured to emit first color light includes a wavelength conversion unit configured to receive the first color light emitted by the excitation light source and emit second color light with a wavelength different from a wavelength of the first color light, There is a first optical system having a positive power and a second optical system having a positive power provided in this order in an optical path between the excitation light source and the wavelength conversion unit. When a ray parallel to an optical axis of the first optical system is incident on the first optical system, a ray emitted from the first optical system is incident on the second optical system while approaching the optical axis. The second optical system has under-corrected spherical aberration at a paraxial focal position of the second optical system.
