Process of making reinforced lenticular sheet

Abstract

Abstract A PROCESS OF FORMING A LENTICULAR SHEET FOR USE IN INTEGRAL PHOTOGRAPHY HAVING AN INTERMEDIATE APERTURED METAL SHEET WHICH ACTS AS A REINFORCING MEMBER AND/OR AS A DIAPHRAGM AND/OR AS A FIELD-LIMITING MEMBER, THE APERTURES BEING COAXIAL WITH THE LENSLETS OF THE LENTICULAR SHEET IN WHICH THEY ARE EMBEDDED OR WITH WHICH THE SHEET IS ASSOCIATED. PREFERABLY, THE DIAPHRAGM LAYER IS A THIN APERTURED METAL LAYER BONDED ON A SECOND THICKER METAL LAYER, IN CERTAIN INSTANCES, THE THIN LAYER BEING PROVIDED WITH DIAPHRAGM APERTURES AT THE PRINCIPAL POINTS OF THE LENSLETS WHILE THE THICKER LAYER HAS LARGER APERTURES, WHICH SERVE AS CLEARANCE APERTURES. IN CERTAIN INSTANCES A SECOND METAL SHEET SIMILAR TO THE FIRST SHEET MAY BE PROVIDED WITH THE APERTURES SERVING AS FIELD-LIMITING APERTURES, IN WHICH CASE THEY ARE PREFERABLY HEXAGONAL. THE REINFORCED LENTICULAR SHEETS ACCORDING TO THE PRESENT INVENTION MAY BE USED FOR TAKING THE ORIGINAL PHOTOGRAPHS IN INTEGRAL PHOTOGRAPHY, FOR CONVERTING THE PSEUDOSCOPIC IMAGE OF A HOLOGRAM, OR OF AN INTEGRAL PHOTOGRAPH INTO AN AUTOSTEREOSCOPIC INTEGRAL PHOTOGRAPH, AND ALSO IN CERTAIN INSTANCES FOR VIEWING INTEGRAL PHOTOGRAPHS.
