Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
83 words
A detector array for sensing electromagnetic radiation of a predetermined wavelength directed thereto by an associated optical system including: a plurality of individual detector elements, in a contiguous arrangement, each producing an electrical charge in response to the amount of electromagnetic radiation being direct to said individual detector elements; and means for summing the electrical charge present on each detector element with the charge present on its immediately adjacent detector element and providing a summed output signal for each pair of adjacent elements.
Claim 2
Dependent Claim
83 words
A detector array for sensing electromagnetic radiation of a predetermined wavelength directed thereto by an associated optical system including: a plurality of individual detector elements, in a contiguous arrangement, each producing an electrical charge in response to the amount of electromagnetic radiation being direct to said individual detector elements; and means for summing the electrical charge present on each detector element with the charge present on its immediately adjacent detector element and providing a summed output signal for each pair of adjacent elements.
