  • Patent number: 11106276
    Abstract: A virtual reality (VR) headset adjusts the phase of light of a virtual scene received from a display element using a spatial light modulator (SLM) to accommodate changes in vergence for a user viewing objects in the virtual scene. The VR headset receives virtual scene data that includes depth information for components of the virtual scene and the SLM adjusts a wavefront of the light of the virtual scene by generating a phase function that adjusts the light of the virtual scene with phase delays based the depth values. Individual phase delays shift components of the virtual scene based on the depth values to a target focal plane to accommodate a user at a vergence depth for a frame of the virtual scene. Further, the SLM can provide optical defocus by shifting components of the virtual scene with the phase delays for depth of field blur.

  • Patent number: 11054590
    Abstract: A process is provided for the high-yield heterogeneous integration of ‘quantum micro-chiplets’ (QMCs, diamond waveguide arrays containing highly coherent color centers) with an aluminum nitride (AlN) photonic integrated circuit (PIC). As an example, the process is useful for the development of a 72-channel defect-free array of germanium-vacancy (GeV) and silicon-vacancy (SiV) color centers in a PIC. Photoluminescence spectroscopy reveals long-term stable and narrow average optical linewidths of 54 MHz (146 MHz) for GeV (SiV) emitters, close to the lifetime-limited linewidth of 32 MHz (93 MHz). Additionally, inhomogeneities in the individual qubits can be compensated in situ with integrated tuning of the optical frequencies over 100 GHz. The ability to assemble large numbers of nearly indistinguishable artificial atoms into phase-stable PICs is useful for development of multiplexed quantum repeaters and general-purpose quantum computers.

  • Patent number: 10156829
    Abstract: The present invention can realize both a transmission type and a reflection type, and provides a holographic microscope which can exceed the resolution of the conventional optical microscope, a hologram data acquisition method for a high-resolution image, and a high-resolution hologram image reconstruction method. In-line spherical wave reference light (L) is recorded in a hologram (ILR) using spherical wave reference light (R), and an object light (Oj) and an illumination light (Qj) are recorded in a hologram (IjOQR) using a spherical wave reference light (R) by illuminating the object with an illumination light (Qj, j=1, . . . , N) which is changed its incident direction. From those holograms, a hologram (JjOQL), from which the component of the reference light (R) is removed, is generated, and from the hologram, a light wave (hj) is generated.

  • Patent number: 9712794
    Abstract: A projector has a light source, image forming units, a projection lens, a first optical system and a second optical system. The image forming units form image light by adjusting, on a per-pixel basis, the intensity of light emitted by the light source. The projection lens projects the image light formed by the image forming units to the outside. The first optical system guides light of a first wavelength emitted by the light source to the projection lens, and the second optical system guides light of a second wavelength emitted by the light source to the projection lens. The f-number of the first optical system is higher than the f-number of the second optical system.
