We present the diffraction pattes observed in the gradient-index (GRIN) lens sensor experiment. Then the diffraction patte of radial GRIN lens is explored by using matrix optics. The theoretical results agree with the experimental results of 27.9-mm-long GRIN lens with 2-mm diameter diffraction pattes.
