To this end, the Hunan team investigated how layers within these structures could manipulate the polarization states of light beams in different ways. To achieve this, they fabricated their bifocal ...

one with left-handed and one with right-handed circular polarization. The liquid crystal cell layer also enables the bifocal lenses to rapidly change foci intensity in response to an external voltage.

A third experiment showed that the team's lenses were sensitive to light polarization, a trait that had not been demonstrated in liquid crystal lenses before. Bees are thought to use this ...

They are also insensitive to polarization – which is sometimes an advantage ... in the case of a pattern-alignment liquid-crystal lens,” explains Yokoyama. “That has to be solved in order to make this ...

Using liquid crystal polarization grating lenses (LCPG lenses) in combination with controllable liquid crystal (LC) switches, we were able to show focus changes of more than 500 micrometers in less ...

Liquid crystal (LC) lenses with electrically tunable focal length have attracted ... LC layers must be thickened by means of a multilayered LC structure that exhibits polarization independence, large ...
