A three-dimensional imaging system uses apertures through which images are projected. The image through each aperture is obtained by a different camera element. The camera elements can be totally physically separate, multiple receiving parts of a single camera, or a single camera which is effectively spatially modulated so that the single camera receives different images at different times. The outputs from the camera are used to form three-dimensional information about the object.
