Paper Abstract
We propose using the time multiplexing super resolution method in order to extend the depth of focus of an imaging system. In standard time multiplexing the super resolution is achieved by generating duplication of the optical transfer function in the spectrum domain by using moving gratings. By changing the grating's frequency, and by that changing the duplication positions, it is possible to obtain an extended depth of focus. Using the same concept, it is also possible to correct geometrical aberrations of the imaging lens. The proposed method is presented analytically, demonstrated via numerical simulations, and validated by a laboratory experiments.
