1. An optical interrogation system comprising:
- a launch system for directing an array of light beams towards an array of sensors in a two-dimensional specimen plate; and
a receive system including;
a beam expander; and
a detector;
said beam expander for receiving the array of said light beams reflected from the array of sensors, and for reducing the dimension of the array of said light beams and directing each received light beam to a unique region on a detection plane in said detector, wherein said detector is located past an image plane associated with said beam expander for the purpose of measuring response angles in the array of said light beams reflected from the array of sensors in the two-dimensional specimen plate.
