Abstract

A new method is developed for recording and reconstructing a microscopic high-resolution 3-D image with large depth. Any imaging lens is not located between the object and the CCD in our optical system. A number of partial off-axis holograms are sequentially recorded with one CCD, or are recorded at once with multi-channel CCD by the single- shot digital holography. Partial complex-amplitude in-line holograms are extracted from recorded off-axis holograms by applying the simple-shot digital holography, and are arranged in order to generate a wide complex-amplitude in-line hologram. A high-resolution image with no distortion is numerically reconstructed from the wide complex-amplitude inline hologram.
