Paper Abstract

The experimental measurements of enhanced backscattering for a laser beam propagating through random screens is presented here. A 10 cm collimated laser beam was transmitted through a random phase screen and reflected back through the same screen by a mirror placed in the near field behind the screen. The laser beam was then imaged at infinity and the averaged scattered intensity was measured. Directly in the backscattered direction an enchancement peak was observed. The width of this peak was near the diffraction limit, while the height was about a factor of two larger than the normal large scattering element observed from phase screens.
