1. A system for monitoring chemical or biochemical reactions in real time comprising:
- a substrate comprising a plurality of discrete signal sources, each discrete signal source configured to carry out a chemical or biochemical reaction, wherein fluorescence emission from each discrete signal source changes as the chemical or biochemical reaction progresses, and wherein the plurality of discrete signal sources are arranged in substantially parallel rows;
an excitation source;
an optical train configured to direct excitation radiation to the substrate and to image the fluorescent emissions from the signal sources onto an array detector, whereby the optical train is configured to divide the excitation light into multiple parallel beams, each beam having a line illumination profile, wherein the peaks of the line illumination profile correspond to rows in the array of signal sources.

Abstract
Methods and systems for real-time monitoring of optical signals from arrays of signal sources, and particularly optical signal sources that have spectrally different signal components. Systems include signal source arrays in optical communication with optical trains that direct excitation radiation to and emitted signals from such arrays and image the signals onto detector arrays, from which such signals may be subjected to additional processing.

16. A system for monitoring chemical or biochemical reactions in real time comprising:
-
a substrate comprising at least a first subset of signal sources positioned in a first substantial linear orientation, and a second subset of signal sources positioned in a second substantially linear orientation that is substantially parallel to the first linear orientation, the signal sources configured to carry out a chemical or biochemical reaction, wherein fluorescence emission from each discrete signal source changes as the chemical or biochemical reaction progresses; an excitation source; an optical train configured to direct excitation radiation to the substrate and to image the fluorescent emissions from the signal sources onto an array detector, the excitation radiation comprising at least a first and a second substantially parallel linear illumination profile, wherein the first linear profile illuminates the first subset of signal sources and the second illumination profile simultaneously illuminates the second subset of signal sources. - View Dependent Claims (17, 18, 19, 20)
