摘要： Provided is a near-to-eye display device, comprising: a display panel, a light-splitting layer on a light-exit side of the display panel, an imaging lens group on the side of the light-splitting layer away from the display panel, a phase delay layer on the side of the display panel away from the light-splitting layer, a transflective layer on the side of phase delay layer away from display panel. The display panel comprises multiple display units, some of which emit first linearly-polarized light, the others emit second linearly-polarized light; first linearly-polarized light transmits through the light-splitting layer and is imaged on a first focal plane by the imaging lens group, second linearly-polarized light is reflected by the light-splitting layer and transflective layer, is subjected to polarization state transition through the phase delay layer, finally transmits through light-splitting layer and is imaged on a second focal plane by the imaging lens group.

摘要： An eyepiece suitable for a night vision device, having an optical combiner for injecting a synthetic image onto the scene and having a single optical correction mechanism is provided herein. The eyepiece may include an observer-side lens; an objective-side lens; a diopter adjustment knob configured to set a distance between the observer-side lens and the objective-side lens; and an optical combiner located between the objective-side lens and the objective-side lens, wherein the optical combiner reflects towards the observer-side lens, the synthetic image transmitted from outside the eyepiece and transfers towards the observer-side lens, a scene image coming from an objecting lens of the night vision device and passing through the objective side lens, and wherein the diopter adjustment knob serves as a single setting mechanism which simultaneously sets a diopter of the observer and a focal depth of the display source image.

摘要： The present invention relates to an eyepiece optical assembly, system and device. The assembly includes a first optics group, a second optics group and a third optics group arranged in sequence along an optical axis from a human eye viewing side to a miniature display. The first optics group includes a first lens group, a first polarizer group and a first waveplate group, the second optics group includes a second lens group and a transflective optical surface, and the third optics group includes a third lens group, a second waveplate group and a second polarizer group. Imaging light is emitted from the miniature display and is reflected and refracted back and forth between the first optics group and the second optics group, and finally exits from the first optics group close to the human eye viewing side into a human eye for imaging.

摘要： The image display apparatus includes an image capturing optical system, an image sensor, a display element, and an ocular optical system. An optical axis of the image capturing optical system and an optical axis of the ocular optical system are located on a same straight line. An image capturing view angle of the image capturing optical system is larger than a display view angle of the ocular optical system. The display element is configured to display, of an image generated by using a signal from the image sensor, an area corresponding to the display view angle. When d represents a distance between a position of an entrance pupil of the image capturing optical system and a position of the exit pupil of the ocular optical system, the condition of 20 mm≤d≤60 mm is satisfied.

摘要： An optical instrument for modifying light as a function of selected prisms and anti prisms for generating visible complex geometries. The optical instrument provides a linear arrangement of crystal portions followed by prism portions through which light passes, respectively, before being viewable through an eyepiece. The crystal portions provides a multifaceted crystal prism, a crystal chamber housing a selective arrangement of a plurality of basic crystal polyhedra, and a rotatable transparent sphere. The prism portions provide mirrored and glass surface triangular prisms independently rotatable relative to the longitudinal axis of the optical instrument.

摘要： An optical device 10 comprises an objective lens 11 defining a focal plane FP and an eyepiece 12 spaced apart therefrom, defining an optical axis OA therethrough. The optical device 10 comprises an optical member 13 having a first planar face 14, arranged on the optical axis OA proximal the focal plane FP, wherein the first planar face 14 is arranged to oppose the objective lens 11. The optical device 10 comprises a filter assembly 100 comprising a first notch filter 101 arranged to attenuate transmission of electromagnetic radiation having a first wavelength λ1, wherein the first notch filter 101 is arranged in front of the optical member 13. The first notch filter 101 is arranged at a first oblique angle θ1 to the optical axis OA whereby, in use, incident electromagnetic radiation having a predetermined wavelength λi propagating along the optical axis is reflected by the first notch filter 101 away therefrom, wherein the first wavelength λ1 and the predetermined wavelength λi are different. In this way, retro-reflection of the incident electromagnetic radiation towards a source thereof is reduced, thereby better detection of the optical device 10.

摘要： A head-mounted device may have a head-mounted housing. Optical components may be supported by the head-mounted housing. The optical components may include cameras such as front-facing cameras and/or movable optical modules that have displays for displaying images to eye boxes. Sensors may be provided in the head-mounted device to detect changes in orientation between respective optical modules, between respective portions of a chassis, display cover layer, or other head-mounted support structure in the housing, between optical components such as cameras, and/or between optical components and housing structures. Information from these sensors can be used to measure image misalignment such as image misalignment associated with misaligned cameras or misalignment between optical module images and corresponding eye boxes.
