Compensator for multiple surface imaging
First Claim
1. A method for detecting a biological sample, comprising:
- (a) detecting radiation emitted from a first emissive component of a biological sample disposed on a first surface of a multi-surface support structure using a detector;
(b) inserting corrective optics between the detector and the multi-surface support structure; and
(c) detecting radiation emitted from a second emissive component of a biological sample disposed on a second surface of the multi-surface support structure using the detector and the corrective optics, wherein the first and second surfaces are in an arrangement whereby one of the surfaces is disposed between the detector and the other surface, wherein the corrective optics reduce aberration of detection at one of the surfaces due to the arrangement.

Abstract
A system and method for imaging biological samples on multiple surfaces of a support structure are disclosed. The support structure may be a flow cell through which a reagent fluid is allowed to flow and interact with the biological samples. Excitation radiation from at least one radiation source may be used to excite the biological samples on multiple surfaces. In this manner, fluorescent emission radiation may be generated from the biological samples and subsequently captured and detected by detection optics and at least one detector. The detected fluorescent emission radiation may then be used to generate image data. This imaging of multiple surfaces may be accomplished either sequentially or simultaneously. In addition, the techniques of the present invention may be used with any type of imaging system. For instance, both epifluorescent and total internal reflection methods may benefit from the techniques of the present invention.
