Abstract: Technologies are generally described for phase measuring profilometry (PMP) using structured light patterns based on orthogonal frequency division multiplexing (OFDM). In some examples, a composite structured light pattern generated using OFDM may be used to illuminate a surface of interest. The surface may reflect a phase-distorted version of the structured light pattern, and the phase-distorted structured light pattern may be processed to recover image and/or height information about the surface. In some embodiments, fast Fourier transform schemes may be used to generate the composite structured light pattern and process the phase-distorted structured light pattern.

Abstract: An approach for projecting light may be implemented using a acousto-optical depth switch that uses surface acoustic waves produced along a substrate to guide image light to different areas. The surface acoustic waves may be generated on a substrate using a transducer. Surface acoustic waves of different frequencies can guide image light onto different optical elements at different physical positions. The optical elements may be configured to show objects in an image at different distances from a viewer.

Abstract: Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.

The first rolling shutter direction may be parallel to and the same as the second rolling shutter direction. A first image may be obtained from the first image sensor. A second image may be obtained from the second image sensor. A stitched image may be generated based on the first image and the second image.
