Microlens Arrays for Shack Hartmann Sensors

A Shack Hartmann sensor measures the intensity profile
and the wavefront of coherent light in real time and
with high accuracy. The sensor divides an incident wavefront into a number of beamlets by the sub apertures of
a microlens array.
Each microlens provides a separate focus on the sub grid
of detectors on a CCD camera. The analysis of the resulting pattern is used to measure the optical phase of an
incident wavefront.
Applications include measurements on astronomical t
instruments, adaptive optics, wavefront compensation,
and the eye itself. Jenoptik provides unique microlens array solutions with high spatial resolution for Shack Hartmann sensors. These microlens arrays can be designed
for wavefronts with large or small phase depths.
