摘要： 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.

摘要： A system for projecting dots onto a three-dimensional image is configured to activate multiple pseudo-random dot projectors sequentially. Each pseudo-random dot projector includes an illumination source and a wavefront modulating element (WME) located along an optical axis in a path traversed by radiation produced by the illumination source. The system is configured to form images of dots in the projection plane along the optical axis. The system may also include controlling circuitry configured to perform a sequential projection operation on the plurality of pseudo-random dot projection systems to produce a temporal sequence of images and aggregate and process the temporal sequence of images to produce a high-resolution depth image of the three-dimensional surface.

摘要： In some implementations, a camera includes an image sensor, a first portion configured to receive light along a first optical axis, a second portion that includes a plurality of lens elements that share a second optical axis that is different from the first optical axis, a reflective element arranged to alter a path of light entering the camera in a direction along the first optical axis to a direction along the second optical axis towards the image sensor, at least two independent actuators configured to tilt the reflective element about a pivot point, and one or more resilient elements configured to bias a position of the reflective element.
