Abstract
Provided herein is an apparatus including a photon emitter array. The photon emitter array includes a number of photon emitters selectively oriented in a number of polarized orientations. The photon emitters are configured to controllably emit photons onto a surface of an article. The apparatus also includes a photon detector positioned to receive photons scattered from features on the surface of the article. The photon detector simultaneously receives photons oriented in the number of polarized orientations. In addition, the photon detector provides information for mapping the features on the surface of the article.
Claims7
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, and
- a 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;
- and
- a photon detector configured to receive photons scattered from features on the surface of the article, wherein the photon detector provides information for mapping the features on the surface of the article.
