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 ...

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

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 ...

so it measures the ways in which the observed spot differs and calculates how to change the mirror's surface so it will reflect a perfect spot, as expected. Adaptive optics systems generally run ...

The use of deformable mirrors to correct unwanted optical aberrations in real time is helping applications ranging from astronomy to biophotonics and data storage, reports Neil Savage. Adaptive ...
