Paper Abstract

A new principle to obtain sectional images of a thick specimen by a conventional optical microscope without physically slicing is developed. The optical microscope with an off-axis pupil is used to project a 3-D distribution of the specimen in various directions within the numerical aperture of the objective lens. Since the system is the strictly angularly-limited one, a strong constraint is needed to reconstruct the 3-D structure from the projections. The conjugate gradient method with the object boundary constraint which is a priori known meets this problem. Experimental results with a biological sample verify the capability of the proposed method as optical tomography of microscopic size.
