Microlens Arrays for Shack Hartmann Sensors

nnnn

A Shack Hartmann sensor measures the Intensity profile

nnnn

and the wavefront of coherent light In real time and

nnnn

with high accuracy. The sensor divides an Incident wave-

nnnn

front Into a number of beamlets by the sub apertures of

nnnn

a microlens array.

nnnn

Each microlens provides a separate focus on the sub grid

nnnn

of detectors on a CCD camera. The analysis of the result-

nnnn

ing pattern Is used to measure the optical phase of an

nnnn

Incident wavefront.

nnnn

Applications Include measurements on astronomical

nnnn

Instruments, adaptive optics, wavefront compensation,

nnnn

and the eye Itself. Jenoptlk provides unique microlens ar-

nnnn

ray solutions with high spatial resolution for Shack Hart-

nnnn

mann sensors. These microlens arrays can be designed

nnnn

for wavefronts with large or small phase depths.
