We propose a light field hologram generation algorithm based on Fourier slice theory. This algorithm uses Fourier slices to reform the light field images into a naturally continuous autofocusing images in three dimensional space. Then, by employing Stochastic Gradient Descent (SGD), we calculate the phase-only hologram based on diffraction propagation. Our experiment shows that a light field hologram is demonstrated with authentic defocus blur effects.
