1. An optical radiation receiver system, comprising:
a prism;
a sensor to detect optical radiation; and
a tunable optical metasurface steerable to:
receive optical radiation through an upper face of the prism at a target steering angle, and
transmit the received optical radiation to be internally reflected within the prism before passing through the prism to be received by the sensor.
