The correction speed is mainly limited by the camera's frame rate. However, it is also dependent on other factors, including the speed of the deformable mirror and its controller, number of spots in the Shack-Hartmann pattern, number of DM actuators and available light level.
With Basler A602f camera we achieved correction rates up to 90 Hz at a full frame and up to 380 Hz at an area of interest of 128x128 pixels. Correction rates up to 440 Hz were achieved with Andor DU-860 fast EMCCD camera.
Using of multiprocessor and multiple-core PCs is recommended for highest performance.
