Previous methods have struggled to transfer this angular momentum efficiently and independently of the light's specific properties. The OSCILLIGHT project offers an original solution by exploiting the vector nature of angular momentum, a property that has been previously overlooked for technological innovation.
Initially, "oscillight" was a technical term synonymous with a cathode-ray tube (CRT) oscillograph. Patents from the 1930s, particularly those by television pioneer Philo T. Farnsworth, refer to an "oscillight or cathode ray oscillograph" used for capturing transient electrical phenomena and, crucially, for receiving television signals.
