Patent ID: 7456940

Claim:
An apparatus for determining information related to one or more optical sources comprising: at least two gratings for diffracting radiation received from said optical source, for which a first of said gratings is oriented relative to a second of said gratings such that said diffracted radiation created by a first of said gratings is rotated ninety degrees relative to said diffracted radiation created by a second of said gratings; at least two lenses, each of said lenses positioned to receive said diffracted radiation created by a respective one of said at least two gratings; at least two detectors, each of said detectors positioned to receive said diffracted radiation passing through a respective one of said at least two lenses; and at least one processing unit coupled to said at least two detectors for receiving data related to said diffracted radiation received by said at least two detectors and performing at least one of the group consisting of locally processing said data, transmitting said data for remote processing, recording said data for remote processing, and combinations thereof; wherein a first indexing system of a first of said detectors is rotated ninety degrees relative to a second indexing system of a second of said detectors.
