We experimentally demonstrate a light-field moment microscopy (LFMM). The proposed technique employs a better estimation of the intensity derivative in solving the Poisson equation and therefore can significantly reduce the noise and error in the reconstructed light-field moment. The light field can be reconstructed then by using the moment, enabling the perspective view and depth estimation of the object. The proposed LFMM can be simply implemented using a standard commercial light microscope. This will open up new possibility for standard microscopes in high-resolution light-field observations.
