Abstract

Panoramic camera scanning system including a rotating mirror system which enables scanning through a full 360° revolution. The mirror system includes a planar mirror member having reflective coatings on both of its surfaces. This planar member is mounted so as to extend along an axis in a direction substantially perpendicular to the optical axis of a camera utilized within the scanning system. By rotating the planar member, a full 360° scanning view can be provided to the camera without requiring any movement of the camera.

Claims

1. Mirror system for use in a panoramic camera scanning system comprising:

a planar member having reflective coatings on both of its planar surfaces;

means for rotatably mounting said planar member so that its plane lies along an axis extending in a direction substantially perpendicular to the optical axis of a camera utilized in the scanning system; and

,

means for rotating said planar member about said mounting axis.

2. A system as defined in claim 1 wherein said rotating means continuously rotates said planar member through a full 360°

revolution.

3. A panoramic scanning system comprising:

a camera;

a planar member having reflective coatings on both of its planar surfaces;

means for rotatably mounting said planar member so that its plane lies along an axis extending in a direction substantially perpendicular to the optical axis of a camera utilized in the scanning system; and

,

means for rotating said planar member about said mounting axis.

4. A system as defined in claim 3 wherein said camera has a wide-angled lens so that when the plane of said planar member extends in a direction aligned with the optical axis of said camera, said planar member presents no impediment to the optical view of said camera.

5. A system as defined in claim 3 wherein said camera is spaced only a short distance from said mirror.

6. A system as defined in claim 3 wherein when the plane of said planar member extends in a direction perpendicular to the optical axis of said camera the only image viewed by said camera is the reflection from one of said planar surfaces of said planar member.

7. A system as defined in claim 3 wherein when the plane of said planar member extends in a direction perpendicular to the optical axis of said camera, the view reflected by said planar surfaces of said planar member to said camera only covers a portion of the optical view of said camera.

8. A system as defined in claim 3 further comprising further means for mounting said camera, said further mounting means for said camera being coupled to said mounting means for said planar member and said camera being adjustably mounted on said further mounting means such that said camera can be moved in a direction along its optical axis relative to said planar member.

9. A system as defined in claim 3 wherein said rotating means continuously rotates said planar member through a full 360°

revolution.

10. A system as defined in claim 3 wherein said camera is a video camera.
