Abstract
An optical projection tomography system is illuminated with a light source. An object-containing tube, a portion of which is located within the region illuminated by the light source, contains an object of interest that has a feature of interest. A detector is located to receive emerging radiation from the object of interest. A lens, including optical field extension elements, is located in the optical path between the object region and the detector, such that light rays from multiple object planes in the object-containing tube simultaneously focus on the detector. The object-containing tube moves relatively to the detector and the lens operate to provide multiple views of the object region for producing an image of the feature of interest at each view.
