Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
76 words
Apparatus for controlled multiple mode distortion of an electromagnetic radiation element, comprising: at least three posts affixed to the electromagnetic radiation element and extending therefrom; and actuators disposed between said posts for applying variable force therebetween, equal and opposite moments being developed from the force of each said actuator through said posts to distort the electromagnetic radiation element, said posts being located on the electromagnetic radiation element to provide at least two modes of distortion therein.
Claim 2
Dependent Claim
76 words
Apparatus for controlled multiple mode distortion of an electromagnetic radiation element, comprising: at least three posts affixed to the electromagnetic radiation element and extending therefrom; and actuators disposed between said posts for applying variable force therebetween, equal and opposite moments being developed from the force of each said actuator through said posts to distort the electromagnetic radiation element, said posts being located on the electromagnetic radiation element to provide at least two modes of distortion therein.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1 wherein the electromagnetic radiation element is an optical element having a reflective surface and the multiple mode distortion thereof is controlled to vary the contour of said reflective surface.
Claim 4
Dependent Claim
51 words
The apparatus of claim 2 wherein said optical element is in the configuration of a disc with three posts and three actuators symmetrically arranged thereon about the center thereof, the forces applied by said actuators being equal when controlling the focus of said optical element and unequal when controlling the astigmatism.
Claim 5
Dependent Claim
58 words
The apparatus of claim 2 wherein said optical element is in the configuration of a disc with six posts symmetrically arranged thereon about the center thereof and with three actuators arranged thereacross through the center thereof, the forces applied by said actuators being equal when controlling the focus of said optical element and unequal when controlling the astigmatism.
Claim 6
Dependent Claim
51 words
The apparatus of claim 2 wherein said optical element is in the configuration of a disc with six posts and six actuators symmetrically arranged thereon about the center thereof, the forces applied by said actuators being equal when controlling the focus of said optical element and unequal when controlling the astigmatism.
Claim 7
Dependent Claim
70 words
The apparatus of claim 2 wherein said optical element is in the configuration of a disc with six posts symmetrically arranged thereon about a seventh post at the center thereof and six actuators are disposed across the disc between said seventh post and each of said other posts, the forces applied by said actuators being equal when controlling the focus of said optical element and unequal when controlling the astigmatism.
