Shack-Hartmann Wavefront Sensor Demonstration at SPIE Photonics West [e-mail]

Wavefront sensor demonstration at SPIE Photonics West 2013 [e-mail]
The program reconstructs the wavefront from a spot pattern obtained with hexagonal, orthogonal or random Hartmann (-Shack) mask with arbitrary number of subapertures. The software supports standard video interfaces on Windows and Linux. In "Alignment" mode the software is capable of real-time dynamic display of low-order aberrations in polar coordinates or bar-graph format. In the feedback mode, the program couples with deformable mirror and can be used for low-cost real-time adaptive optics.
Software calibrated Hartmann masks with hexagonal and orthogonal geometries, designed to work with 1/2 inch CCD arrays. Can be supplied as a stand-alone component (square 10x10mm) or in a C-mount compatible head.
Wide range of microlens arrays for Hartmann-Shack sensors. Each array can be supplied standalone, or mounted in a C-mount compatible head.
Software is compatible with HR CCD and CMOS cameras with PC video interface for Windows and Linux operating systems.
Closed-loop adaptive optical systems at SPIE Photonics West 2013 [e-mail]
Closed-loop adaptive optical systems for real-time correction of optical aberrations and generation of precision wavefronts.
Applications include scientific instrumentation, astronomy, ophthalmology, laser optics and optical alignment systems.
We supply closed-loop AO systems based on Micromachined Membrane Deformable Mirrors (MMDM) with up to 79 channels and Piezoelectric Deformable Mirrors (PDM) with 19, 37, 79 and 109 channels. Aberration correction is possible in circular, rectangular, annular, elliptic and annular elliptic apertures. The feedback frame rates of 30 ... 1500 fps, depending on the camera and computer used, are sufficient for correction of aberrations caused by the atmospheric turbulence.
Real-time AO phase control is realized by Hartmann-Shack WF sensor, offering a wide variety of control options including SVD eigenmode analysis, mode filtering, operations with the background, etc .
We can also supply deformable mirror systems with linear 19 and 38-ch MMDM and 20-ch PDM for ultrafast pulse shaping. These application-specific systems should be controlled by a customer-made feedback sensors and software.

Adaptive optics - deformable bimorph mirrors and wavefront sensors

Wavefront Sensors: ShaH Family
A family of ShaH wavefront sensors represents recent progress of Del Mar Photonics in Shack-Hartmann-based technology. The performance of Shack-Hartmann sensors greatly depends on the quality of the lenslet arrays used. Del Mar Photonics. developed a proprietary process of lenslet manufacturing, ensuring excellent quality of refractive lenslet arrays. The arrays can be AR coated on both sides without interfering with the micro-lens surface accuracy. Another advantage of the ShaH wavefront sensors is a highly optimized processing code. This makes possible real-time processing of the sensor data at the rate exceeding 1000 frames per second with a common PC. Due to utilizing low-level programming of the video GPU, it is possible to output the wavefront data with a resolution up to 512x512 pixels at a 500+ Hz frame rate. This mode is favorable for controlling modern LCOS wavefront correctors.
The family of ShaH wavefront sensors includes several prototype models, starting from low-cost ShaH-0620 suitable for teaching laboratory to a high-end high-speed model, ShaH-03500. The latter utilizes a back-illuminated EM-gain CCD sensor with cooling down to -100°C. This makes it possible to apply such a wavefront sensor in astronomy, remote sensing, etc.

we do offer Shack-Hartmann wavefront sensor software package - [e-mail]
Specifications:
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, our Shack-Hartmann wavefront sensor software allows calculating control signals for the corrector in the closed-loop mode.
The program package 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.

whats the wavelength spec?

[@delmarphotonics]

I am researching adaptive optics systems for a proposal. The only kicker is that we’d like to do everything at NIR for wavelengths near 1500 nm, which is beyond the sensitivity of silicon.
On the brochure, (www.dmphotonics.com/ShaH_Del_Mar_photonics_web.pdf) there is the statement that “An interface to a variety of CCD and CMOS sensors allows a wide range of acquisition bands from UV to near IR.” Can it interface with an InGaAs camera? I’ve been talking to a different vendor that offers a phosphor coating on the CCD that allows it to respond to 1490 - 1600 nm wavelengths. Do you off anything like that? If not, perhaps we can figure out an appropriate InGaAs camera - I don’t know if you have one you recommend, or I could look around and suggest one to you.
So I have it, could you send me pricing for this package:
a. Part# VC.DMU-38-G-24-MDL-000-HP1,06 Unimorph deformable mirror, 25mm aperture, 24 actuators, +/-6um stroke
b. Part# VC.PDC-24-1-300-100 Control unit, 24 channels, USB, 100Hz bandwidth
c. Part# VC.SHAH-6-150-3-20 Wavefront sensor ShaH (Shack-Hartmann), 6mm aperture, 20Hz frame rate.
d. VC.TL-30-6-1,06 Telescope 5X for wavefront sensor, optimized for 1.06um
e. VC.CLDLL-V2.14 Closed loop software
f. Includes installation and 3 days training
