Time multiplexing based geometrical aberrations correction

The use of the time-multiplexing super-resolution method for extending the depth of focus of an imaging system was recently presented [Opt. Lett.41, 183 (2016)OPLEDP0146-959210.1364/OL.41.000183]. It involved changing the encoding and decoding gratings frequencies, which determine the optical transfer function duplications positions, and by that obtaining an extended depth of focus. In this Letter we expand this method by showing its applicability for correcting geometrical aberrations of an imaging lens. The proposed method is presented analytically, and validated experimentally for chromatic aberration, spherical aberration, and astigmatism aberration.
