Abstract
Abstract An optical device in the form of a light sensor having variable optical attenuation. Attenuation is accomplished by deforming a wall or diaphragm thereby causing a variation of the aperture provided thereby, without changing the angle or axis of the field of view of the sensor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
An optical device for providing optical attenuation of received radiation for an associated optical-to-electrical transducer comprising: a body having first and second chambers, and a deformable member disposed between said first and second chambers, said first chamber being adapted to house an optical-to-electrical transducer, and said second chamber being adapted to receive radiation energy from the exterior of the optical device, and an optically transparent member disposed in said second chamber, and being movable therein for selectively deforming said deformable member for varying the attenuation of the radiation passing from said second to said first chamber without substantially changing the axis of the field of view.
Claim 2
Dependent Claim
106 words
An optical device for providing optical attenuation of received radiation for an associated optical-to-electrical transducer comprising: a body having first and second chambers, and a deformable member disposed between said first and second chambers, said first chamber being adapted to house an optical-to-electrical transducer, and said second chamber being adapted to receive radiation energy from the exterior of the optical device, and an optically transparent member disposed in said second chamber, and being movable therein for selectively deforming said deformable member for varying the attenuation of the radiation passing from said second to said first chamber without substantially changing the axis of the field of view.
Claim 3
Dependent Claim
32 words
The device as in claim 1 wherein said optically transparent member includes threads and is threaded into said second chamber, and has a surface for engaging and thereby deforming said deformable member.
Claim 4
Dependent Claim
21 words
The device as in claim 1 wherein the optical-to-electrical transducer is a light sensor and the radiation energy is light energy.
Claim 5
Dependent Claim
15 words
The device as in claim 1 wherein said body is formed of an opaque plastic.
Claim 6
Dependent Claim
16 words
The device as in claim 1 wherein said deformable wall is integrally formed with said body.
Claim 7
Dependent Claim
16 words
The device as in claim 4 wherein said deformable wall is integrally formed with said body.
Claim 8
Dependent Claim
14 words
The device as in claim 1 wherein said deformable member is a deformable wall.
Claim 9
Dependent Claim
14 words
The device as in claim 2 wherein said optically transparent member is a screw.
Claim 10
Dependent Claim
26 words
The device as in claim 8 wherein said optically transparent member includes a notch which allows said optically transparent member to axially deform said deformable member.
Claim 11
Dependent Claim
13 words
The device as in claim 1 wherein said wall member includes symmetrical sections.
Claim 12
Dependent Claim
19 words
The device as in claim 10 wherein said symmetrical sections form a generally shaped four pointed aperture when deformed.
