A stereo camera, including an imaging sensor, and an optical apparatus comprising first and second apertures separated by an interocular distance and configured to focus first and second images on the imaging sensor in a side by side arrangement. An imaging system including the stereo camera, and at least one image processor, configured to receive first and second frames of image data from a stereo camera, and construct volumetric image data based on binocular disparity between the first and second frames.

An apparatus and method are disclosed to produce a stereoscopic image with a hemispherical field of view. In an implementation, the apparatus includes an optical arrangement to receive first light rays from a first fisheye lens and second light rays from a second fisheye lens. The first fisheye lens and the second fisheye lens are positioned adjacent to each other and an object side of each of the first and second fisheye lenses faces a first plane. The optical arrangement is to direct the first light rays and the second light rays onto an image sensor and bend optical axes of the first and second light rays such that the first light rays are projected onto the image sensor alongside the second light rays.

A distance measurement device includes a first acquisition unit configured to acquire distance information on the basis of a plurality of images captured at different viewpoints, a second acquisition configured to acquire correction information of the distance information on the basis of a plurality of images captured at a timing different from the plurality of images used by the first acquisition unit, and a correction unit configured to correct the distance information on the basis of the correction information.

An image sensor includes a substrate, a first thin lens configured to concentrate light of a first wavelength, and including a plurality of first scatterers disposed on the substrate. The plurality of first scatterers includes a material having a refractive index greater than a refractive index of the substrate. The image sensor further includes a plurality of light-sensing cells configured to sense the light concentrated by the first thin lens.

A stereoscopic camera with fluorescence visualization is disclosed. An example stereoscopic camera includes a visible light source, a near-ultraviolet light source, and a near-ultraviolet light source. The stereoscopic camera also includes a light filter assembly having left and right filter magazines positioned respectively along left and right optical paths and configured to selectively enable certain wavelengths of light to pass through. Each of the left and right filter magazines includes an infrared cut filter, a near-ultraviolent cut filter, and a near-infrared bandpass filter. A controller of the camera is configured to provide for a visible light mode, an indocyanine green (“ICG”) fluorescence mode, and a 5-aminolevulinic acid (“ALA”) fluorescence mode by synchronizing the activation of the light sources with the selection of the filters. A processor of the camera combines image data from the different modes to enable fluorescence emission light to be superimposed on visible light stereoscopic images.
