Patent ID: 8625094

Claim:
A detection system, comprising: a substrate having a plurality of etched channels; a first camera that detects at least a first emission signal of a first wavelength or wavelength range and a second camera that simultaneously detects at least a second emission signal of a second wavelength or wavelength range that is distinct from the first wavelength or wavelength range; and a TDI system that processes signals detected by at least one of the cameras, wherein the first emission signal is emitted from at least one labeled analyte disposed on the substrate and irradiated by a first excitation source, and the second emission signal is simultaneously emitted from at least one labeled analyte disposed on the substrate and simultaneously irradiated by a second excitation source, the first and second excitation sources simultaneously irradiating a first and a second area of the substrate, respectively, the first and second area spatially offset from one another.
