Abstract
Devices, systems, and methods for measuring wave fronts generated by a lens for an eye are provided. In some embodiments, a device for measuring wave fronts generated by a lens for an eye includes a radiation source for emitting test radiation to be directed at the lens and a sensor device for detecting wave fronts of incident test radiation after interaction with the lens, wherein the sensor device scans the test radiation after interaction with the lens at a scanning frequency which is at least equal in size to the frequency at which changes in wave fronts occur in the test radiation after interaction with the lens.
