Optical resonance analysis using a multi-angle source of illumination

摘要

An SPR or other optical resonance based analysis system in which, light is provided at multiple angles to a specimen and then the light modified by the specimen is processed to select only some of the light. Optionally, the processing selects light at a particular incidence angle. Optionally, the detection is by imaging of the light on a 2D imager array.

主权项

1. An optical resonance analysis system, comprising:
at least one light source which emits an illumination; a specimen unit which holds at least one specimen and configured for facilitating interaction between said specimen and said illumination, said illumination providing a plurality of angles of incidence simultaneously, said interacting including one or both of reflecting part of said illumination, and refracting part of said illumination; a detection unit configured to detect at least part of said illumination after said interaction; and a selecting unit which selects only a portion of said interacted light for detection by the detection unit, said portion representing interactions with light at less than a full range of said plurality of angles of incidence and wherein said selecting unit is reconfigured for selecting at least a different one of said portions, at different times.
