Abstract: A tissue oximetry system employing diffuse optical spectroscopy includes an optical subsystem and an electronics and processing subsystem, together generating modulated optical signals processing a response optical signal in order to obtain measurements of blood oxygen values for a tissue from per-wavelength absorption values. Signal sources generate RF modulation signals, and ADC circuitry generates streams of digital sample values from analog detection signals.
