摘要：We need to project coherent laser beams onto an object in order to produce a hologram for a real object.However,this requirement restricts the shooting arrangement in electronic holography.Using integral photography(IP) enables a hologram to be created from a reconstructed IP image,and allows us to electronically display a 3-D image of an object photographed under natural light.We propose a method that employs fast Fourier transform(FFT) to calculate optical transmission during hologram shooting and that requires only half the calculation load required by the conventional method,i.e.,that based on the Fresnel diffraction.We used this method to produce a hologram from an integral photography image of an object photographed under natural light.We then used a liquid crystal device to optically reconstruct a holographic image of the object and evaluated the effectiveness of the method.
