First Claim
Patent Images

1. A method of forming images on a rotating photosensitive substrate, the method comprising:

  • exposing, solely by a single laser beam wavefront lacking interference information, the rotating photosensitive substrate to form a plurality of diffractive elements,wherein a first portion of the plurality of diffractive elements is reconstructable to form a first image viewable at a first angle,wherein a second portion of the plurality of diffractive elements is reconstructable to form a second image viewable at a second angle different from the first angle,wherein the exposing is accomplished without a reference beam impacting the rotating photosensitive substrate, andwherein the exposing is accomplished with one laser beam impact point.
