| Shack-Hartmann Wavefront Measurement and
Lens Arrays
Adaptive Optics Associates, Inc.’s (AOA) wavefront sensors
make measurements similar to interferometers, without requiring
coherent (laser) illumination. As a subsidiary of Northrop
Grumman’s Essex Advanced Optics, AOA used this advanced technology
to test the corrector optics for the Hubble Space Telescope.
AOA’s WaveScope® line of Shack-Hartmann wavefront sensors
detects minute manufacturing errors in lenses and mirrors.
WaveScope performs the same measurements traditionally made
with interferometers, without using a coherent, monochromatic
laser source—it works as well with broadband and incoherent
light.
Typical WaveScope measurement applications:
- Ophthalmic lens distortion
- Wavefront distortion through multiple optical elements
- Deformable mirror surfaces
- Spherical mirror or lens surfaces
- Wavefront of a dynamically changing optical system
This full-featured system incorporates patented techniques
for increased dynamic range (up to 400λ
peak-to-valley full-aperture tilt). Interchangeable lens arrays
can accommodate many different measurements, and its user-programmable
software accommodates a wide variety of uses.
