Researchers have developed a novel experimental platform to measure the electric fields of light trapped between two mirrors with a sub-cycle precision. These electro-optic Fabry-Perot resonators will ...

Evidence suggests ancient civilizations, including the Greeks, may have had early optical knowledge and devices like ...

An adaptive optics system measures the distortion of incoming light and compensates to create sharp, clear images. Light from the telescope bounces off the adaptive mirror and is sent through a ...

But that doesn’t mean there aren’t quick and dirty adaptive optics that are suitable for the budget-minded experimenter, like this thermally deformable mirror. As [Zachary Tong] explains ...

Hot mirrors are heat-reflecting mirrors that are designed to work as a shortpass edge filter by transmitting visible wavelengths @AOI 0°, while reflecting NIR, heat-generating wavelengths.(Reflect NIR ...

Kevin Parry created a simple, yet maddening optical illusion ... did say is that it required nothing more than an iPhone and a mirror. Story by Ian Phillips and editing by Carl Mueller Follow ...
