Abstract
Abstract An optical bulk storage arrangement for a digital computer comprising an information carrier, an image of which is projected by means of objective lens means onto a camera device, e.g.: a television camera tube, having means for temporarily storing the image, means for varying the position of the focal plane of the objective lens means relative to the information carrier between two exposures of the camera device and means for initiating an exposure when the focal plane is just passing through the information carrier.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
130 words
An optical bulk storage arrangement for electronic computers comprising an information carrier, a camera device, an objective lens means for providing in said camera device an image of said information carrier for the readout of said objective lens means, means in said camera device for temporarily storing said image, means for causing said means for temporarily storing to be exposed to said image, means for storing a temporarily stored image for a certain time, means for varying the position of the focal plane of said objective lens means relative to said information carrier between two exposures of said camera device, and means for initiating the exposure of said camera device when said focal plane is just passing through said information carrier and storing an image in said means for storing.
Claim 2
Dependent Claim
130 words
An optical bulk storage arrangement for electronic computers comprising an information carrier, a camera device, an objective lens means for providing in said camera device an image of said information carrier for the readout of said objective lens means, means in said camera device for temporarily storing said image, means for causing said means for temporarily storing to be exposed to said image, means for storing a temporarily stored image for a certain time, means for varying the position of the focal plane of said objective lens means relative to said information carrier between two exposures of said camera device, and means for initiating the exposure of said camera device when said focal plane is just passing through said information carrier and storing an image in said means for storing.
Claim 3
Dependent Claim
16 words
An arrangement as defined in claim 1, wherein said camera device comprises a television pickup tube.
Claim 4
Dependent Claim
26 words
An arrangement as defined in claim 2, wherein said means for varying the position of said focal plane relative to said information carrier is operated periodically.
Claim 5
Dependent Claim
31 words
An arrangement as defined in claim 2, wherein said means for varying the position of said focal plane of said objective lens means comprises means for moving said objective lens means.
Claim 6
Dependent Claim
20 words
An arrangement as defined in claim 2, wherein the duration of a an exposure is less than 1,000 Mu sec.
Claim 7
Dependent Claim
26 words
An arrangement as defined in claim 5, further comprising at least one flash lamp, which lamp delivers appropriate light pulses for obtaining the short exposure time.
Claim 8
Dependent Claim
27 words
An arrangement as defined in claim 5, further comprising at least one spark gap, which spark gap delivers appropriate light pulses for obtaining the short exposure time.
Claim 9
Dependent Claim
27 words
An arrangement as defined in claim 5, further comprising at least one pulsed laser, which pulsed laser delivers appropriate light pulses for obtaining the short exposure time.
Claim 10
Dependent Claim
22 words
An arrangement as defined in claim 2, wherein the duration of an exposure is between 1 Mu sec and 10 Mu sec.
Claim 11
Dependent Claim
54 words
An arrangement as defined in claim 2, further comprising an illuminated diaphragm having an aperture and whose image is projected by said objective lens means on said information carrier and a receiver for measuring the distribution of the light reflected or scattered back from said information carrier on said diaphragm and the diaphragm aperture.
Claim 12
Dependent Claim
18 words
An arrangement as defined in claim 10, wherein said diaphragm is constructed in the form of a mirror.
Claim 13
Dependent Claim
44 words
An arrangement as claimed in claim 11, wherein said diaphragm comprises patterns of alternate transmissive and reflecting portions, the minimum dimensions of which after reproduction by said objective lens means are of the order of magnitude of a pattern dot of said information carrier.
Claim 14
Dependent Claim
42 words
An arrangement as defined in claim 11, wherein said diaphragm comprises alternate transmissive and reflecting strips, the minimum dimensions of which after reproduction by said objective lens means are of the order of magnitude of a pattern dot of said information carrier.
Claim 15
Dependent Claim
15 words
An arrangement as defined in claim 2, wherein said information carrier comprises a reflecting layer.
Claim 16
Dependent Claim
21 words
An arrangement as defined in claim 14, wherein the information is stored in said reflecting layer in the form of holes.
Claim 17
Dependent Claim
25 words
An arrangement as claimed in claim 14, wherein the information is stored in a photographic layer which is coated with a reflecting layer after development.
