Abstract: A broadband light source includes one or more laser diodes that are capable of generating a pump signal having a wavelength shorter than 2.5 microns, a pulse width of at least 100 picoseconds and a pump optical spectral width. The light source also includes one or more optical amplifiers that are coupled to the pump signal and are capable of amplifying the pump signal to a peak power of at least 500W. The light source further includes a first fiber that is coupled to the one or more optical amplifiers. The first fiber including an anomalous group-velocity dispersion regime and a modulational instability mechanism that operates to modulate the pump signal. In one particular embodiment, the pump signal wavelength resides in the anomalous group- velocity dispersion regime of the first fiber and where different intensities in the pump signal can cause relative motion between different parts of the modulated pump signal produced through modulational instability in the first fiber. The light source also including a nonlinear element that is coupled to the first fiber that is capable of broadening the pump optical spectral width to at least 100nm through a nonlinear effect in the nonlinear element.

The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.
