    摘要: In some implementations, an optical device may include an aperture, one or more optical elements, an optical filter, and an optical sensor. The aperture may be configured to receive light. The one or more optical elements may be configured to diffuse the light received by the aperture, direct the diffused light to the optical filter via a folded optical path, wherein a length of the folded optical path is greater than a distance between the aperture and an input surface of the optical filter, and cause the diffused light to be distributed across the input surface of the optical filter. The optical filter may be configured to filter the diffused light distributed across the input surface of the optical filter to pass portions of the diffused light associated with one or more wavelengths to the optical sensor.

    摘要: An optical assembly includes a first substrate and a second substrate that extend parallel to a reference plane and are separated from each other in a direction perpendicular to the reference plane; and a plurality of optical elements that are arranged parallel to the reference plane and include a first metasurface element and a second metasurface element. The first metasurface element is embedded in the first substrate and/or the second metasurface element is embedded in the second substrate. The first metasurface element and the second metasurface element are configured such that one of the first metasurface element and the second metasurface element reflects at least a portion of light to another one of the first metasurface element and the second metasurface element.

    摘要: A pulse width expansion apparatus according to an aspect of the present disclosure includes a polarization beam splitter and a transfer optical system. The transfer optical system includes ¼-wavelength and reflection mirror pairs. The ¼-wavelength mirror pair include first and second ¼-wavelength mirrors. The first ¼-wavelength mirror provides ¼-wavelength phase shift and reflects a pulse laser beam. The second ¼-wavelength mirror provides ¼-wavelength phase shift and reflects the pulse laser beam reflected by the first ¼-wavelength mirror. The reflection mirror pair are disposed on an optical path before and after or between the ¼-wavelength mirror pair. The transfer optical system transfers an image of an input pulse laser beam on the polarization beam splitter to the optical path between the ¼-wavelength mirror pair at one-to-one magnification as a first transfer image and transfers the first transfer image to the polarization beam splitter at one-to-one magnification as a second transfer image.

    摘要: The present technology relates to an imaging apparatus, a manufacturing apparatus, a manufacturing method, and an electronic appliance that contribute to miniaturization and thinning of an imaging apparatus. Provided is an imaging apparatus including a first circuit board in which an imaging element is mounted on a center portion, a component that is mounted on an outer circumference portion of the center portion of the first circuit board, and a member that incorporates the component and is provided in the outer circumference portion and is formed by a mold method. The imaging apparatus further includes a lens barrel that holds a lens, in which a frame that supports a portion including the lens barrel is located on the member. Further, the frame includes an infra red cut filter (IRCF). The present technology can be applied to an imaging apparatus.
