METHOD AND DEVICE FOR OPTICALLY EXAMINING THE INTERIOR OF TURBID MEDIA

摘要

A method for optically examining the interior of turbid media is provided. The method comprises the steps: providing broad-band light (2); spatially separating a plurality of wavelength bands (2a, 2b,..., 2n) contained in the broad-band light; separately modulating the plurality of wavelength bands (2a, 2b,..., 2n); recombining the plurality of modulated wavelength bands to a beam (11) of spectrally encoded broad-band light; illuminating a turbid medium (8) with the beam (11) of spectrally encoded broad-band light; detecting light emanating from the turbid medium (8) with a detector (9) and demodulating the detected light with a demodulator (10) to provide spectroscopic information.
