Abstract

Photon-density wave interference was reconstructed from sequential time-resolved transmittance experiments. The two "interfering” sources were applied one at the time and the results were Fourier transformed, one of them phase shifted by n radians at the desired modulation frequency, and then added to each other. This gives us the possibility to study any modulation frequency we want without repeating the measurement. Apart from providing high spatial resolution, the technique of photon density wave interference gives a high detectability of regions with minor deviations in optical properties.
