The ShaH family of industrial Shack-Hartman wavefront sensors is
intended for a wide range of applications including fast and
precise quality control of optical elements, airflow analysis,
measurement of laser beam parameters, etc. The flexible design
of the ShaH system allows optimizing the sensor parameters for a
particular application. An advantageous feature of the device is
the use of high-quality telescopes. This allows minimizing the
influence of the angle of incidence of the analyzed beam on the
instrumental function of the sensor. A special high-precision
algorithm for locating hartmannogramm spots centers provides
high accuracy of measurements even in difficult viewing
conditions. The SDK (C++) allows to operate all functions of the
sensor and to achieve easy integration with user software. |

ShaH program package is
intended for measuring a wavefront by means of ShaH wavefront
sensors. Measurement data are both represented in a realtime and
stored for further post-processing and analysis.
Output:
• Raw Hartmann images
• Spot shift map
• Wavefront aberration map (3D plot, 2D projection,
synthesized interferogram, up to 66 Zernike polynomials)
• Measurement error map
• PSF (point spread function)
• MTF (modulation transfer function)
• Strehl ratio, M2 factor, Gauss-Hermite modes
• Turbulence parameter estimation (for free space measurements)
Statistical analysis can be carried out during post-processing.
If the system is equipped with a wavefront corrector, the ShaH
software allows calculating control signals for the corrector in
the closed-loop mode.
The program package Shah is
distributed as a self-installing executable file and/or a C++
SDK, which grants access to all functionality of the sensor and
allows complete customization useful to the user’s software.

• The optional program module “M2-sensor” is intended both for
measurements of intensity and phase profiles and for estimation
of the M2 factor of a single-mode laser beam on the basis of the
wavefront measurement data. M2 calculations are carried on
according to ISO 11146-2 standard. The module also permits
expansion of the multimode beam into Gauss-Hermite modes in both
automatic and manual regimes.
• The optional program module “Beam propagation” is intended for
simulation of the beam propagation starting from the wavefront
sensor input plane to the plane located at a doubled distance to
the plane of the beam waist. |
