Real Time Holographic Image Processing
Abstract
We have proposed homodyne and heterodyne techniques for imaging in a scattering medium. The first technique is based on the principle of the Doppler shift difference of the light which is scattered from an object vs light scattered by the surroundings. We showed that the principle of Doppler shift difference, and the principle of first arriving light are similar. However, in contrast to first light, which requires ultrafast pulses, here modulated CW can be used. We also experimentally demonstrated the basic principle for a simple case of an object outside of the scattering medium. The second is an extension of the principle of photon density waves, using a two-dimensional (non-scanning) detection scheme.
