Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
A PICTURE RECORDING METHOD WHICH COMPRISES THE STEPS OF: CASTING WITHIN CAMERA MEANS SHADOWS OF A SHADOWING RETICLE WITH INVESIBLE RADIATION HAVING A WAVELENGTH OF LESS THAN 1000 A. FROM A POINT SOURCE CONFIGURATION EXTERNAL TO THE RECTICLE CAMERA MEANS, THE DIMENSIONS OF SAID RETICLE AND OF SAID CAMERA MEANS, AND WAVELENGTHS OF SAID RADIATION BEING SO RELATED THAT FOCUSING AND DIFFRACTION EFFECTS ARE ESSENTIALLY EXCLUDED; FORMING A FAITHFUL REPLICA OF THE PATTERN OF SAID RETICLE SHADOWS AS CAST WITH SAID RADIATION WITHIN THE FIELD OF VIEW TO BE RECORDED; AND OPTICALLY RECONSTRUCTING SAID PATTERN OF SAID REPLICA OF THE RETICLE SHADOWS BY USING EACH RETICLE SHADOW REPLICA AS AN OPTICAL ELEMENT FOR CONCENTRATING VISIBLE RECONSTRUCTION RADIATION INTO POINTS CORRESPONDING TO SAID ORIGINAL POINT SOURCES, SAID RECONSTRUCTION RADIATION BEING OF A WAVELENGTH CONVENIENT FOR USE IN ORDINARY PHOTOGRAPHIC AND OPTICAL PRACTICE.

Claim 3
Dependent Claim
79 words
RETICLE PHOTOGRAPHY COPYING APPARATUS COMPRISING: AN ARRAY OF FRESNEL FOCUSING ZONE PLATE MEANS HAVING A MULTIPLICITY OF FOCI AT DIFFERENT AXIAL DISTANCES, AND PRODUCED AS A RECORD BY EXPOSURE TO INVISIBLE RADIATION THROUGH A SHADOWING RETICLE; A SOURCE OF VISIBLE LIGHT; MEANS FOR DIRECTING A BEAM OF LIGHT FROM SAID SOURCE TOWARDS SAID RECORD FOR FOCUSING THEREBY OF RESPECTIVE PORTIONS OF THE BEAM ON SEVERAL PLANES THEREBEYOND ON AN OPTICAL SURFACE IN A SELECTED ONE OF SAID PLANES; AND
