Paper Abstract

An out-of-focus coherent image of a transilluminated particle in a transparent field is actually an in-line hologram of that particle. In the Fresnel field of the particle's cross-section, direct measurement of the particle diameter can be achieved with considerable effective defocus -- much greater than the depth of focus with an incoherent imaging system.
