Claim Text:
1. A system comprising: a detecting component configured to detect incident electromagnetic radiation at a number of pixels; a number of electromagnetic radiation sources; each electromagnetic radiation source emitting at substantially one wavelength from a number of wavelengths; at least some of the number of wavelengths substantially coinciding with wavelengths in an absorption spectrum of predetermined materials; each one of the number of the electromagnetic radiation sources sequentially illuminating an area of interest; the number of electromagnetic radiation sources emitting substantially from one location; the detecting component receiving reflected/scattered electromagnetic radiation from the area of interest; a modulating component configured to modulate, with respect to time, emission from said each one of the number of electromagnetic radiation sources; a timing component configured to provide a signal for initiation of emission from a selected one of the number of electromagnetic radiation sources; the timing component also configured to provide said initiation signal for initiating detection by the detecting component; and an analysis component configured to:
