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 ...

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 latest deformable mirror from Edmund Optics (Barrington, New Jersey, USA) consists of 32 radially arranged actuators that control the shape of a 5-μm-thick nitrocellulose mirror membrane.

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 ...
