abstract

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. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
