1. A method of evaluating biological tissue, the method comprising:
- during a first period, sequentially illuminating using one or more sources at least a first portion of a biological tissue being evaluated with a plurality of bands of electromagnetic energy in a first sequence, wherein at least one of the sources provides two or more of the plurality of bands of electromagnetic energy;
during the first period, measuring a plurality of responses to the illumination from at least the first portion of the biological tissue being evaluated;
comparing the measured responses of the first period to a first set of reference responses to illumination of a reference specimen of biological tissue; and
identifying the portion of biological tissue based at least in part on the comparison of the measured responses of the first period to the first set of reference responses.

Abstract
Spectral information may be employed in process control and/or quality control of goods and articles. Spectral information may be employed in process control and/or quality control of media, for example financial instruments, identity documents, legal documents, medical documents, financial transaction cards, and/or other media, fluids for example lubricants, fuels, coolants, or other materials that flow, and in machinery, for example vehicles, motors, generators, compressors, presses, drills and/or supply systems. Spectral information may be employed in identifying biological tissue and/or facilitating diagnosis based on biological tissue.
