Abstract: Devices and methods are described herein for providing foveated image projection. In general, at least one source of laser light is used to generate a laser beam, and scanning mirror(s) that reflect the laser beam into a pattern of scan lines. The source of light is controlled to selectively generate projected image pixels during a first portion of the pattern of scan lines, and to selectively generate depth mapping pulses during a second portion of the pattern of scan lines. The projected image pixels generate a projected image, while the depth mapping pulses are reflected from the surface, received, and used to generate a 3-dimensional point clouds that describe the measured surface depth at each point. Thus, during each scan of the pattern both a projected image and a surface depth map can be generated, with the surface depth map used to modify some portion of the projected pixels.

Abstract: Devices and methods are described herein for combining image projection with surface scanning. In general, the devices and methods utilize at least one source of laser light to generate a laser beam, and scanning mirror(s) that reflect the laser beam into a pattern of scan lines. The source of light is controlled to selectively generate projected image pixels during a first portion of the pattern of scan lines, and to selectively generate depth mapping pulses during a second portion of the pattern of scan lines.
