1. An ingestible scanning device, comprising:
- an ingestible capsule housing having a transparent window;
a one-dimensional photo-sensing array comprising at least one photosensor located within the capsule housing;
a mirror located within the housing and oriented to direct an image from a surface outside the transparent window to the photo-sensing array;
a light source for illuminating the surface outside the transparent window,wherein at least one of the mirror and the one-dimensional array is movable with respect to the housing; and
a cylindrical lens between the photo-sensing array and the mirror, the cylindrical lens being oriented so that its axis is parallel to the photo-sensing array to direct light from the mirror onto the photo-sensing array.
