A method of recording a holographic record is described. According to this method, a holographic recording medium is exposed to a desired pattern, shape, or image from a coherent light source emitting light at one or more wavelengths to which the holographic recording medium is sensitive. In this method, light having the desired pattern, shape, or image to which the holographic recording medium is exposed is diffracted by a spatially homogeneous optical diffraction element so that the holographic recording medium is exposed to a plurality of interfering light beams, thereby forming a holographic record in the holographic recording medium. Holographic recording articles are described that include a holographic recording medium and a spatially homogeneous optical diffraction element. |
