It's also possible to steer light electromagnetically using a spatial light modulator, but the angular range would be very narrow.
- anfractuosity 3y agoHave you come across AOM too - https://en.wikipedia.org/wiki/Acousto-optic_modulator https://en.wikipedia.org/wiki/Acousto-optic_modulator, they appear to be able to control the angle of light also.
