1. An optical device or scanner for monitoring fluorescence signals emitted from a surface of a medium, the fluorescent signals varying in intensity across the surface, the optical device or scanner comprising:
- an adaptive spectral filter including a spatial light modulator that selectively modulates the fluorescent signals, the spatial light modulator modulating the fluorescent signals emitting from at least one spatial location of the surface based upon an intensity of the fluorescent signals emitting from the corresponding spatial location, wherein the optical device or scanner records an image using multiple fluorescence tags that indicate a degree of binding or hybridization of target biomolecules to probes immobilized on the medium which is used in an assay process, and wherein the adaptive spectral filter is controlled to be spectrally matched to a first fluorescent signal spectrum and is then adjusted to be spectrally matched to a second fluorescent signal spectrum that is different from the first fluorescent signal spectrum.

Abstract
The present invention features incorporating an adaptive spectral filter into a confocal scanner optical arrangement or other suitable optical device to permit real time control of the fluorescence signal spectrum being monitored. This new arrangement would allow for better balancing of the fluorescence signals in the analysis of the array.

11. A method for monitoring fluorescence signals emitted from a surface of a medium, the fluorescent signals varying in intensity across the surface, the method comprising:
-
positioning an adaptive spectral filter to receive the fluorescent signals emitted from the medium, the spectral filter comprising a spatial light modulator; and selectively modulating the fluorescent signals emitted from the surface of the medium with the spatial light modulator, the fluorescent signals emitted from at least one spatial location of the surface being modulated based upon an intensity of the fluorescent signals emitted from the corresponding spatial location; recording, at the optical device or scanner, an image using multiple fluorescence tags that indicate a degree of binding or hybridization of target biomolecules to probes immobilized on the medium which is used in an assay process; controlling the adaptive spectral filter to be spectrally matched to a first fluorescent signal spectrum; and adjusting the adaptive spectral filter to be spectrally matched to a second fluorescent signal spectrum that is different from the first fluorescent signal spectrum. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
