Abstract

A method including providing a device that projects a pattern of coherent radiation. The method further includes capturing a reference image of the pattern using an image sensor by projecting the pattern of the coherent radiation onto a reference surface and engendering a relative motion between the reference surface and the image sensor while capturing the reference image. The method also includes storing the reference image in a memory associated with the device.
