Optical measurement and interference techniques

The procedure of manufacturing of a diffuse screen for the projection of 3D images that reproduce the horizontal parallax only is presented. The optical properties of such screen are considered. The screen represents a diffusor that is capable of scattering the light in the vertical direction only. The screen is fabricated by means of photographical recording of a pattern of speckles generated by a vertical luminous thin line. The details of the chemical treatment of the exposed photograph of the pattern are considered. The measurements of optical properties of the screen have shown that the chemical treatment ensured the suppression of the zero order in the scattered light. The mechanism of 3D image projection when using the screen is considered.
