First Claim
1. A moving imager camera comprising:
- a first positioning mechanism capable of three-dimensional movement;
a first imaging device having an imaging surface, the first imaging device being mounted upon a surface of the first positioning mechanism such that the first imaging device moves in concert with motion of the surface of the first positioning mechanism;
a first measurement system operable to determine a position of the first imaging device within an external frame of reference defined by three axes X, Y, and Z; and
a first lens having a focal surface and a field of coverage, the first lens arranged such that the focal surface coincides with the imaging surface of the first imaging device, the field of coverage of the first lens being larger than the optically sensitive area of the imaging surface. a second positioning mechanism capable of three-dimensional movement;
a second imaging device having an imaging surface, the second imaging device being mounted upon a surface of the second positioning mechanism such that the second imaging device moves in concert with motion of the surface of the second positioning mechanism;
a second measurement system operable to determine a position of the second imaging device in the focal plane; and
a second lens having a focal surface and a field of coverage, the second lens arranged such that the focal surface of the second lens coincides with the imaging surface of the second imaging device, the field of coverage of the second lens being larger than the optically sensitive area of the imaging surface.

Abstract
A precision motion platform carrying an imaging device under a large-field-coverage lens enables capture of high resolution imagery over the full field in an instantaneous telephoto mode and wide-angle coverage through temporal integration. The device permits automated tracking and scanning without movement of a camera body or lens. Coupled use of two or more devices enables automated range computation without the need for subsequent epipolar rectification. The imager motion enables sample integration for resolution enhancement. The control methods for imager positioning enable decreasing the blur caused by both the motion of the moving imager or the motion of an object'"'"'s image that the imager is intended to capture.
