Optical wavefront sensor

These wavefront sensors (Shack-Hartmann type)

allow to obtain a map of local slopes of the analysed

wavefront with the help of a microlenses array.

This principle used for a long time in astronomy was

amply improved as well on hardware as on software.

The CCD detectors reached the maturity and the

necessary quality/price ratio to certify an

irreproachable metrology with moderate prices;

the fabrication of microlenses arrays has become reliable.

The software innovations of Imagine Optic allow to use

trough optimal way this simple and direct measurement.
