Outline of Final Research Achievements

A fast and high-resolution self-interference incoherent digital holography system was developed using a fast phase-shifting method with a continuous fringe scanning scheme. Randomly phase-shifted holograms created by the self-interference of wavefront diffracted from objects illuminated by the incoherent light source were analyzed by a generalized phase-shifting method. The normalized generalized phase-shifting method using hologram normalization was porposed. The conditions for high-speed phase-shifting are verified. The resolution power and the processing speed of the incoherent digital holographysystem were evaluated. The effectiveness of the proposed incoherent digital holography system was demonstrated by optical experiments for micro objects.
