We propose 'digital cloaking' as a method for practical cloaking, where space, angle, spectrum, and phase are discretized. At the sacrifice of spatial resolution, a good approximation to an 'ideal' cloak can be achieved-A cloak that is omnidirectional, broadband, operational for the visible spectrum, three-dimensional (3D), and phase-matching for the light field, among other attributes. Experimentally, we demonstrate a two-dimensional (2D), planar, ray optics version of our proposed digital cloak by using lenticular lenses, similar to 'integral imaging' for 3D displays. With the continuing improvement in commercial digital technology, the resolution limitations of a digital cloak will be minimized, and a wearable cloak can be developed in the future.
