Paper Abstract

In this paper we explore potential applications of a new transparent Electro-Optic Ceramic in 3D imaging as a fast phase shifter and demonstrate its performance in a newly developed Low Coherence Polarization Interference Microscopy (LCPIM). The new phase modulator is fast, convenient and inexpensive. It makes the 3D imaging system that employs it mechanically efficient and compact. The LCPIM proposed in this paper has the advantages of rapid phase shifting and adjustable reference/objective intensity ratio for maximum contrast. The new phase modulator has been approved feasible by several experiments.
