Abstract
Abstract An arrangement is disclosed, in form of various embodiments, for more rapid scanning of an addressed point in space with programmable angular relationships, using either merely rotary motion for angle and reduced motion for position in two or three dimensions, or simply rotary motion for displacement with a consistent angular relationship in two or three dimensions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
Arrangement for scanning an addressed point in space, comprising: a light source; a camera at which light from a light source is directed; deflector means interposed between said source and camera and through which light can pass from the source to the camera; and rotary addressing mirror means in the path of the light intermediate said deflector means and camera, so that light from the source is deflected by the addressing mirror means, from there to the addressed point in space, and from there via the deflector means and the addressing mirror means to the camera.
Claim 2
Dependent Claim
96 words
Arrangement for scanning an addressed point in space, comprising: a light source; a camera at which light from a light source is directed; deflector means interposed between said source and camera and through which light can pass from the source to the camera; and rotary addressing mirror means in the path of the light intermediate said deflector means and camera, so that light from the source is deflected by the addressing mirror means, from there to the addressed point in space, and from there via the deflector means and the addressing mirror means to the camera.
Claim 3
Dependent Claim
23 words
Arrangement as defined in claim 1, said deflector means comprising a concave mirror and said addressing mirror means comprising a single reflecting mirror.
Claim 4
Dependent Claim
54 words
Arrangement as defined in claim 1, said deflector means comprising a pair of lenses, one interposed between said source and addressed point and the other interposed between said addressed point and camera, said addressing mirror means comprising two rotary addressing mirrors each interposed between one of said lenses and said source and camera, respectively.
Claim 5
Dependent Claim
35 words
Arrangement as defined in claim 1, said deflector means comprising a lens, and said addressing mirror means comprising a single addressing mirror interposed in the light from said source, between the same and said lens.
Claim 6
Dependent Claim
56 words
Arrangement as defined in claim 1, wherein said deflector means comprises two concave mirrors each having at its zenith an opening for passage of light said addressing mirror means comprising two rotary addressing mirrors each turnably mounted at the focal point of the respective concave mirror in the path of light travelling through the respective opening.
Claim 7
Dependent Claim
67 words
Arrangement as defined in claim 1, wherein said deflector means comprises a pair of lenses each interposed between the addressed point and one of said source and camera, respectively, said addressing mirror means comprising a pair of addressing mirrors each interposed between one of said lenses and said source and camera, respectively, and each turnable about a pivot intersected by the principal axis of the associated lens.
