A modest increase in image quality was observed with polarized dermatoscopes vs ambient-light dermatoscopes for patient-performed teledermoscopy.

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. Left and right circularly polarized light, where the ...

Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic ...

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...
