ETH Zurich’s bidirectional pixel can both create and read light, pointing to screens that double as cameras, plus holography and optical computing.

We're always looking at screens—but what if screens could someday look back at us?

ETH Zurich researchers have found a way to both emit and analyze light from the same surface.

ETH Zurich’s bidirectional pixel can both create and read light, pointing to screens that double as cameras, plus holography and optical computing.

Un team dell'ETH di Zurigo ha realizzato il primo pixel bidirezionale, il Fourier pixel: genera luce e la analizza nello stesso elemento, fase e polarizzazione incluse. � il primo…
