title: Angular selectivity of silver halide transmission noise gratings copied into dichomated gelatin.
abstract: Transmission noise gratings were copied from silver halide emulsion into dichromated gelatin in an index matching tank. The distance between the two plates was varied to alter the angulars pread of recordeds catter in the dichromated gelatin plate. Results are presented in the form of angular transmittance data and scattering rings which show that the diffraction efficiency and angular selectivity of the transmitted noise decrease with a reduction in noise gratings recorded at high angles.
