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.

Abstract: Optical apparatus includes a device package, with a radiation source contained in the package and configured to emit a beam of coherent radiation. A diffractive optical element (DOE) is mounted in the package so as to receive and diffract the radiation from the radiation source into a predefined pattern comprising multiple diffraction orders. An optical detector is positioned in the package so as to receive and sense an intensity of a selected diffraction order of the DOE.
