Abstract
Methods, systems and devices are described that enable simultaneous measurement of the direction and polarization of electromagnetic waves. One example device includes a first, a second and a third detector, each configured to receive and measure an irradiance of an incoming electromagnetic radiation, and each are positioned such that their normal vectors point in a first, a second and a third direction that are different from one another. At least one of the detectors is further configured to obtain polarization information associated with the incoming electromagnetic radiation. The measured irradiances from the first, the second and the third detectors and the obtained polarization information enable identification of the direction of propagation and polarization state of the incoming electromagnetic radiation.
