Abstract
In this research, two-wave coupling in photorefractive lithium niobate crystal has been used to do imaging enhancement of digital holography (DH) system. The image bearing beam of in-line DH system has been incident and interfered with a reference beam that was emerged from the same laser on a LiNbO3 crystal. With certain angles between both beams, the energy of the reference beam was transferred to the image bearing beam then resulted the enhancement of the reconstructed image of the DH system. By using the suitable intensity of laser beam with a right PR crystal, the image from an in-line DH imaging system would be improved.
