Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
Optical means for space exploration, comprising: a plurality of convergent lenses having substantially the same focal length, means for disposing said lens such that their vertices lie substantially on an arc of a first circle with a radius smaller than the aforesaid focal length and such that their optical axes are substantially convergent at the center of the said first circle so that the foci of the said lenses are disposed substantially on a second circle concentric with said first circle, photosensitive analysis means, and an optical deviating system disposed in the vicinity of the center of the said circles for deviating the images given by the said lenses in the direction of said photosensitive analysis means.
Claim 2
Dependent Claim
117 words

Claim 3
Dependent Claim
17 words
The optical means according to claim 1, wherein said photosensitive means are disposed in a fixed manner.
Claim 4
Dependent Claim
23 words
The optical means for space exploration according to claim 1, wherein said deviating optical system comprises a field diaphragm for the said lenses.
Claim 5
Dependent Claim
20 words
The optical means for space exploration according to claim 1, wherein said photosensitive means are provided with a field diaphragm.
Claim 6
Dependent Claim
42 words
The optical means for space exploration according to claim 1, wherein said deviating optical system comprises a mirror having a rotational movement about an axis passing through the center of the said circles and perpendicular to the plane of the said circles.
Claim 7
Dependent Claim
48 words
The optical exploration means according to claim 1, wherein said lenses each comprise a spherical segment defined by two meridianal planes and two parallel planes situated on either side of the center of this sphere and perpendicular to the diameter defined by the intersection of two meridianal planes.
Claim 8
Dependent Claim
14 words
The optical exploration means according to claim 1, wherein the lenses are biconvex lenses.
Claim 9
Dependent Claim
13 words
The optical means according to claim 1, wherein said lenses are meniscus lenses.
Claim 10
Dependent Claim
14 words
The optical exploration means according to claim 1, wherein said lenses are planoconvex lenses.
Claim 11
Dependent Claim
40 words
The optical exploration means according to claim 1, further comprising a laser generator and a deflection device synchronized with said deviating system, for directing said beam in a controllable manner onto the spatial object for reflection onto said deviating system.
