Abstract: A light-modifying portion divided into a plurality of discrete subareas each of which is occupied by an assigned light-modifying form, such as a prism of selected inclination, produces a pattern in accordance with a code of output light beams during decoding which manifests the code. The meridional angle of the form may also be assigned in accordance with the code. Redundancy is optionally obtainable in that the total plurality of subareas may be divided into groups of subareas, each member of one particular group possessing the same selected inclination and meridional angle and by using an imaging lens during decoding to focus ones of the output light beams derived from the total plurality of discrete subareas to a common focus point.

Abstract: A plurality of separate angularly-disposed beams of wave energy, such as light, can be combined into a single composite beam of wave energy by simultaneously illuminating a holographic beam coupler with the plurality of angularly-disposed beams. The holographic beam coupler is prepared by recording each of a plurality of interference pattern components on a recording medium to form a resultant composite interference pattern on the medium. Each interference pattern component results from illuminating the recording medium with a different pair of angularly disposed beams of coherent wave energy, with the orientation and angle of incidence of one of the beams (the reference beam) of each of the plurality of pairs with respect to the medium being the same as each other and the orientation and angle of incidence of the other of the beams of each of the plurality of pairs with respect to the medium being different from each other and from that of the reference beam of each of the pairs.

Abstract: SPUTTER ETCHING HAS BEEN FOUND TO BE CAPABLE OF TRANSFERRING HOLOGRAMS RECORDED ON A PHOTOSENSITIVE SURFACE LAYER COVERING AN UNDERLYING SUBSTRATE MATERIAL FROM THE LAYER TO THE SUBSTRATE MATERIAL ITSELF. THE TRANSFERRED HOLOGRAM IS IN THE FORM OF A RELIEF PATTERN. THIS TECHNIQUE PROVIDES BOTH HIGH FIDELITY AND HIGH RESOLUTION CAPABILITIES IN BOTH THE DEPTH DIMENSION AND IN THE SURFACE DIMENSIONS OF THE TRANSFERRED RELIEF-PATTERN HOLOGRAM, WHICH ARE IN THE ORDER OF ONE MICRON OR LESS, AND IS APPLICABLE TO OTHER FINE-DETAIL RELIEF PATTERNS.
