Abstract

Abstract An imaging arrangement has a first lens array with a focal surface and a tapered optical fiber bundle arranged with one end face coincident with the focal surface of the lens array. Another end of the bundle is coincident an optical device. The optical device may be a second lens array, an image capture device, a photographic plate, or an electronic image capture device such as a CCD array. The fiber bundle may comprise a single graded index fiber connecting the first and second lens arrays. An integral transmission screen may be provided to project a spatially inverted integral image onto the first lens array.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 43 words
An imaging arrangement comprising: a first lens array having a focal surface; a tapered optical fibre bundle arranged with one end face coincident with the focal surface of the lens array and another end of the tapered fibre bundle coincident an optical device.
Claim 2
Dependent Claim 43 words
An imaging arrangement comprising: a first lens array having a focal surface; a tapered optical fibre bundle arranged with one end face coincident with the focal surface of the lens array and another end of the tapered fibre bundle coincident an optical device.
Claim 3
Dependent Claim 16 words
An imaging arrangement according to claim 1, in which the focal surface comprises a focal plane.
Claim 4
Dependent Claim 39 words
An imaging arrangement according to claim 1, in which the tapered fibre bundle has a second end face, and the optical device is a second lens array that comprises a second focal surface coincident with said second end face.
Claim 5
Dependent Claim 18 words
An imaging arrangement according to claim 3, in which said second focal surface comprises a second focal plane.
Claim 6
Dependent Claim 29 words
An imaging arrangement according to claim 3, in which the fibre bundle is coherent and connects the focal surfaces of corresponding lenses in the first and second lens arrays.
Claim 7
Dependent Claim 27 words
An imaging arrangement according to claim 3, in which multiple fibres of the bundle connect the focal surfaces of corresponding lenses of first and second lens arrays.
Claim 8
Dependent Claim 27 words
An imaging arrangement according to claim 3, in which a single graded index fibre connects the focal surfaces of corresponding lenses in the first and second arrays.
Claim 9
Dependent Claim 26 words
An imaging arrangement according to claim 1, in which the fibre bundle has a second end face adapted to be contacted by an image capture device.
Claim 10
Dependent Claim 17 words
