We present a simple diffraction experiment with fractal gratings based on the Triadic Cantor Set. Diffraction by fractals is proposed as a motivating strategy for the students of optics about the potential applications of optical processing. The Fraunhofer diffraction patterns were obtained with the standard equipment present in most undergraduate physics labs and compared with that obtained with conventional periodic gratings. It is shown that fractal gratings produce self-similar diffraction
