Photon emitter array

摘要

Provided herein is an apparatus, including at least two photon emitters, each with a preselected polarization orientation, and configured to emit polarized photons onto a surface of an article, and a processing means configured to process photon-detector-array signals corresponding to photons scattered from surface features of the article, and generate one or more surface features maps for the article from the photon-detector-array signals corresponding to the photons scattered from the surface features of the article.

1. An apparatus comprising:
a photon emitter array comprising
a first plurality of photon emitters configured to emit coherent and polarized photons oriented at a first polarization orientation onto a location of a surface of an article, anda second plurality of photon emitters configured to emit coherent and polarized photons oriented at a second polarization orientation onto the surface of the article, wherein the second plurality of photon emitters emit onto the same location of the surface as the first plurality of photon emitters; a photon detector configured to receive photons scattered from features on the surface of the article; and a mapping means for mapping the features on the surface of the article based on information received from the photon detector.
