Abstract
Abstract A radiation sensitive device comprising several rings and a middle section formed by a conventional charge coupled device. Drain means for radial draining of the charges generated in the circular sections by the incident radiation and drain means for the charge coupled device are provided. The device has a retina-like structure and can be advantageously applied in robotics.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
Radiation-sensitive device, comprising: a plurality of radiation-sensitive elements in a substantially circular arrangement, the radiation-sensitive elements having a density that decreases radially, each radiation sensitive element generating an electrical signal in response to radiation; drain means for draining electrical signals; and transfer means for coupling the electrical signals from the radiation-sensitive elements to the drain means.
Claim 2
Dependent Claim
56 words
Radiation-sensitive device, comprising: a plurality of radiation-sensitive elements in a substantially circular arrangement, the radiation-sensitive elements having a density that decreases radially, each radiation sensitive element generating an electrical signal in response to radiation; drain means for draining electrical signals; and transfer means for coupling the electrical signals from the radiation-sensitive elements to the drain means.
Claim 3
Dependent Claim
25 words
Radiation-sensitive device as claimed in claim 1, wherein each radiation sensitive element comprises a circular charge-coupled device, and the radiation sensitive elements are arranged concentrically.
Claim 4
Dependent Claim
16 words
Radiation-sensitive device as claimed in claim 2, wherein the circular charge-coupled device includes a three-phase control.
Claim 5
Dependent Claim
36 words
Radiation-sensitive device as claimed in claim 1, wherein the radiation sensitive elements are arranged to form a plurality of ring segments, each ring segment comprising a plurality of radiation-sensitive elements in the form of a circle.
Claim 6
Dependent Claim
16 words
