Improvement of recording capability of silver halides emulsions by physical development

The authors aim to improve the bandwidth of reflection holograms. The parameters influencing the efficiency of the physical developer were optimized by measuring the modulation transfer function of sinusoidal reflection gratings. Changing the conditions of the physical development, the reflectance spectra of Denisyuk type reflection holograms were systematically recorded to measure the position of maximum reflection and bandwidth. In all the experiments Agfa-Gevaert 8E75 HD emulsions were used.<
