Patent ID: 7304724

Claim:
A diffuse optical spectroscopy device for obtaining the optical properties of a sample comprising: a computer; a first light source operatively connected to the computer; a first source optical fiber coupled to the first light source at one end and configured to illuminate the sample with light from the first light source at another end; a detector operatively connected to the computer; a first detector optical fiber coupled to the detector at one end and configured to receive light from the sample; a second broadband light source operatively connected to the computer; a second source optical fiber coupled to the second light source at one end and configured to illuminate the sample with light from the second broadband light source at another end; a spectrometer operatively connected the computer; a second detector optical fiber coupled to the spectrometer at one end and configured to receive light from the sample; and a diffuser interposed between the first source optical fiber and the sample, the diffuser comprising a material having a reduced scattering coefficient greater than 9 mm −1 .
