1. A method of monitoring a plurality of spectrally distinct optical signals from a source of optical signals, comprising:
- passing the plurality of optical signals through an optical train that is configured to image each of the plurality of spectrally distinct optical signals onto an imaging detector that comprises a plurality of pixels, wherein an image of each spectrally distinct optical signal produces a shape of an aggregate group of pixels that is characteristic of the optical signal'"'"'s spectral characteristics;
imaging the plurality of optical signals onto the imaging detector; and
identifying each optical signal by the shape of the aggregate group of pixels characteristic of that optical signal.

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.
