Imaging properties of a 2D crossed holographic grating on silver halide photoemulsions

A technique is proposed for photochemical processing of photoemulsions, which makes it possible to form lens-shaped focusing elements at the nodes of crossed 2D holographic gratings (2DHGs). The results of experiments on 2DHG recording performed on PFG-01 material using this technique show considerable improvement of imaging properties of 2DHG.
