IN-VIVO IMAGING DEVICE WITH DOUBLE FIELD OF VIEW AND METHOD FOR USE
First Claim
1. An in-vivo imaging device comprising:
- a source for illumination; and
an optical imaging system comprising;
a two-dimensional detector array;
a wide field of view imaging system for providing a first image of an object on said detector array, said first image having a first magnification relative to said object; and
a narrow field of view imaging system for providing a second image of part of said object on said detector array, said second image of part of said object having a second magnification substantially greater than said first magnification,wherein said narrow field of view imaging system comprises lenses disposed axially within said wide field of view imaging system, and wherein both of said imaging systems utilize at least one common lens to project an image onto said detector array.

Abstract
An in-vivo imaging device incorporating a double field of view imaging system, having a wide field of view with moderate magnification, and a narrow field of view with substantially higher magnification, axially superimposed thereon. A single imaging array is used for both fields of view. At least some of the optical elements are shared between both of the two different field of view imaging systems. The imaging elements for the high magnification system, being of substantially smaller diameters than those of the low magnification system, are disposed coaxially with the imaging elements of the low magnification system, and can thus use the same imaging array without the need for deflection mirrors, beam combiners or motion systems. Their location on the axis of the low magnification system means that a small part of the imaging plane, around its central axis, is blocked out by the high magnification components.
