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.
Claims1
A device for measuring wave fronts generated by a lens for an eye, comprising:
- a radiation source comprising at least one source for laser radiation emitted at a fixed preset wavelength, the radiation source configured to emit test radiation to be directed at the lens;
- and
- a sensor device configured to:
- detect wave fronts of the test radiation after interaction with the lens, changes in the wave fronts occurring in the test radiation at a wave front changing frequency;
- and
- detect the test radiation at a scanning frequency that is at least equal to the wave front changing frequency.
