Sensorless adaptive optics for microscopy

WebAdaptive optics (AO) is a technique that corrects for optical aberrations. It was originally proposed to correct for the blurring effect of atmospheric turbulence on images in ground-based telescopes and was instrumental in the work that resulted in the Nobel prize-winning discovery of a supermassive compact object at the centre of our galaxy. WebmuDM deformable mirror for microscopy and ophthalmology is a single-piece designed Deformable Mirror containing 91 electromagnetic actuators, disposed in an optimized pattern, and a communication card used as a controller. Versatile, it can be implemented …
