Abstract

We describe a novel method of optical diagnostics of tissues with ballistic photons. They are selected by detecting them in an interferometric setup, further using heterodyning to increase the signal size. Three strategically placed apertures select the beam diameter for spatial resolution in scanning, and the angle within which the partially scattered photons might be collected. We model inclusion inside a bone-like object as a treelayer tissue that includes the skin, the muscle, and the bone. We calculate the size of detected inclusion as a function of limiting signal to noise ratio.
