Abstract:
A method of imaging an object in medium, wherein said object is a tumor and said turbid medium is a tissue, said method comprising the steps of:(a) illuminating at least a portion of the turbid medium with substantially monochromatic light of a first wavelength, said illuminated portion of the turbid medium comprising the object, said first wavelength being selected from the group consisting of a wavelength in the range of 940-1010 nm, a wavelength in the range of 1120-1240 nm, and a wavelength in the range of 1400-1500 nm; (b) wherein each of the turbid medium and the object has a resonance wavelength for an optical property, wherein the respective resonance wavelengths for the turbid medium and the object are different for said optical property and wherein said substantially monochromatic light of said first wavelength is equal in wavelength to the resonance wavelength for said optical property of one of the turbid medium and the object; (c) using at least a portion of the light emergent from the turbid medium to form an image of the object in the turbid medium.
