title: Photosensitive characteristics of the optical information storage element using M centers in NaF crystals.
abstract: Effects of M-center concentration and thickness of the M-center layer on the photosensitive characteristics of optical information storage elements using M centers in NaF crystals are presented. It is shown that writing in the disordering mode and reading with crossed polarizers in white light provide good contrast and gray scale images just like conventional silver halide film.
