title: Phase-contrast volume holographic imaging system.
abstract: A phase-contrast volume holographic imaging system for three-dimensional contrast enhancement is presented. The system utilizes a spatial filter placed on a conjugate plane to the volume holographic pupil to simultaneously enhance weak phase information at different depths within an object. The proposed system was validated with experimental image data obtained in mouse colon samples and quantitative measurements of modulation transfer function as well.
