Chandan, Ganesh G and Vasu, Ram M and Asokan, S (2001) Direct measurement of phase of foreward-scattered light using polarization heterodyne interferometer. In: Proc. SPIE, 4596 (280).Full text not available from this repository.
We describe direct measurement of phase of ballistic photons transmitted through objects hidden in a turbid medium using a polarization interferometer employing a rotating analyzer. The unwrapped phase difference measurements from interferometry was possible for medium levels of turbidity and accurate phase measurement from the sinusoidal intensity was not detectable when l/l* is increased beyond 4.3. The measured phase on reconstruction using standard tomographic algorithms resulted in the recovery of the refractive index profile of the object hidden in the turbid medium.
