Method, apparatus, and article to facilitate evaluation of objects using electromagnetic energy

摘要

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.

主权项

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.
