A device and method for optically examining the interior of turbid media including acts of spatially separating a plurality of wavelength bands contained in a broad-band light； separately modulating the plurality of wavelength bands； recombining the plurality of modulated wavelength bands to a beam of spectrally encoded broad-band light； illuminating a turbid medium with the beam of spectrally encoded broad-band light； detecting light emanating from the turbid medium with a detector and demodulating the detected light with a demodulator to provide spectroscopic information.
