Spatial differentiation is a form of optical computation which has applications in image processing. Here, the authors exploit nontrivial topological charges in the transfer function to realise broadband isotropic two-dimensional differentiation.

For specific problems, analog optical computing can be faster and more computationally efficient than digital methods. Here, Zhuet al. simplify the often metamaterial-based approach to a single thin metal film, with which they demonstrate spatial dif

For phase-only spatial light modulators (SLMs), it is necessary to calibrate phase-response curves in various applications with light wavefront shaping. Here we develop a method to calibrate the global phase-response curve, based on the generalized o

Optical spatial differentiation is important for applications in massively parallel computing and real-time image processing. This study makes use of the generalized spin Hall effect of light to perform optical spatial differentiation. Importantly, t

Phase is a fundamental resource for optical imaging but cannot be directly observed with intensity measurements. The existing methods to quantify a phase distribution rely on complex devices and structures. Here we experimentally demonstrate a phase

We show that the interference effects associated with surface plasmon excitations at a metal-dielectric interface can perform spatial differentiation. Utilizing it, we experimentally demonstrate edge detection of images without any Fourier lens. This
