Abstract:
An adapter is provided for adapting an optical instrument, such as a camera (3) or a projector, to capture or display panoramic three-dimensional images. The adapter comprises a plurality of mirrors (1a, 1b, 1c), each of which has a reflective surface which is in the shape of a curved non-circular conic section rotated about an axis of symmetry (15a, 15b, 15c). The reflective surfaces have first foci which are spaced perpendicularly from a longitudinal axis of the adapter and which are angularly spaced around the longitudinal axis. For example, the conic section may be a hyperbola with first foci equidistantly spaced from the longitudinal axis and equiangularly spaced around the longitudinal axis. The axes of symmetry (15a, 15b, 15c) of the mirrors (1a, 1b, 1c) converge to intersect the longitudinal axis at a point which is coincident with the front principal point of, for example, a camera lens (12). Thus, single shot capture of all the image data for the or each panoramic three-dimensional image may be performed.
Abstract:
A 3D camera for acquiring and recording a plurality of 2D images of single scene at different viewing angles is disclosed. The camera includes taking lenses (13 and 14), exposure stations (63 and 64), a diaphragm stop (23 and 24) with light transmission windows (33 and 34), a window-moving device, and a shutter (10). Lenses are side by side in a row so that optical axes (313 and 314) of lenses are parallel to each other. Exposure stations are behind and in registry with the taking lenses respectively so as to place 2D image-recording means thereat for exposure to light rays transmitted through taking lenses. The diaphragm stop is alongside the row of taking lenses to restrict light rays from exposure stations. The windows of the diaphragm stop are located respectively opposed to the taking lenses for transmitting light rays such that only light rays transmitted through windows reach the stations to form 2D images. The window-moving device functions to move the windows along the row of taking lenses to adjust the distance between adjacent windows.
Abstract:
Certain aspects relate to systems and techniques for folded optic stereoscopic imaging, wherein a number of folded optic paths each direct a different one of a corresponding number of stereoscopic images toward a portion of a single image sensor. Each folded optic path can include a set of optics including a first light folding surface positioned to receive light propagating from a scene along a first optical axis and redirect the light along a second optical axis, a second light folding surface positioned to redirect the light from the second optical axis to a third optical axis, and lens elements positioned along at least the first and second optical axes and including a first subset having telescopic optical characteristics and a second subset lengthening the optical path length. The sensor can be a three-dimensionally stacked backside illuminated sensor wafer and reconfigurable instruction cell array processing wafer that performs depth processing.
Abstract:
A polarization plenoptic camera that can acquire the polarization information of reflected light from an object in a single shot; i.e., in real time, to avoid issues such as motion blur and also avoid the additional system complexity that derives from mechanical scanning of a polarizer. The camera includes a polarization-sensitive focal plane array, a first microlens array having a pitch that is equal to a pitch of the pixel array; and either a second microlens array having a pitch that is greater than the pitch of the pixel array, a coded aperture mask, or a second microlens array and a coded aperture mask. A method for obtaining a plenoptic image of an object scene is disclosed.

Abstract:
A device for creating more natural three-dimensional image effects which may be recorded, for example, by video cameras. The device has an intermittent image pathway occluder for receiving at least two image pathways which alternately and intermittently occludes the two image pathways, a horizontal imaging-shifting component for shifting at least one of the image pathways leftward or rightward, a vertical imaging-shifting component for shifting the image pathways upward and downward, and an image pathway compositing component which forms a coincident superimposed composite three-dimensional image after the image pathways have been shifted by the horizontal and vertical imaging-shifting components, and after passing through the intermittent image pathway occluder. Also, a device for enhancing the more natural three-dimensional effect of such images which are created and which may be recorded and/or displayed.
