Unleash the full power of our wavefront metrology software
The user-friendly design makes it possible to get the most out of optical metrology with our HASO™ wavefront sensors and the HASO R-Flex 2 metrology systems. WaveView4 provides an intuitive software environment with tailored workspaces for specific applications required in production configurations.
New features of WaveView4:
- SpotTracker: a new technology that allows you to use certain HASO wavefront sensors without alignment and access to an absolute measurement of tilts without any ambiguity in a range of 6 degrees.
- Customizable workspaces ideal for production environments or multi-user configuration. Once the interface is configured to fit to your needs (with proper settings and displays) you can save this workspace. When you reopen the workspace, the software is immediately 100% operational as you want it to be.
- User several HASO wavefront sensors with one computer at the same time
- Autosave wavefronts or define a script for sequential acquisition to track changes over time
- Easily define a custom pupil with the new pupil design tool
- Easy comparison of wavefront maps by opening them on several windows simultaneously.
Behind the updated interface, a powerful functionality unique to the HASO line of products awaits you. Using only one program you can measure phase and intensity simultaneously and independently, reconstruct the wavefront using either zonal or modal methods, examine the spot diagram in detail, or use the PSF* to get detailed information on beam focusing. All of this information provided about the wavefront enables you to understand why other components are not performing as expected, and can help you track down problems faster by locating their source.
WaveView displays all key parameters of your beam in real time:
- X- and Y-tilts
- Focal point position in three dimensions
- Radius of curvature
- Raw camera signal
- Wavefront or phase map
- Intensity map
- Spot diagram
- Zernike or Legendre coefficients
- and many more…
Zonal & modal wavefront reconstruction
Wavefront reconstruction is performed by using the information on local slopes acquired using our patented Shack-Hartmann technology. With WaveView, you can choose to reconstruct the wavefront using either zonal or modal methods and represent it using known polynomials – Zernike for circular and Legendre for rectangular pupils.
Zonal reconstruction allows you to visualize the wavefront using the highest spatial resolution that the sensor can provide. Modal reconstruction allows for a decomposition of the wavefront on an orthogonal basis, allowing you to understand the aberrations present in the optical system.
The history function available in WaveView is useful to monitor the temporal evolution of parameters, such as wavefront RMS, radius of curvature, Zernike coefficients etc., in real time. The selected values are plotted as a function of time, along with a display of the mean and RMS values of the data in the graph. The data can be exported in text format for additional processing.
Scripted and sequential acquisition modes
You can record sequential wavefronts throughout the duration of your experiment at user-defined time intervals. This permits the study of long-term variation of beam parameters, ex. the evolution of the radius of curvature overnight. Wavefront data is recorded automatically and can be reviewed using a replay function in WaveView.
This functionality is also useful for monitoring short-lived events. In script mode, you can define the desired acquisition frequency to be up to 1 kHz to measure the evolution of the wavefront.
Options: PSF and MTF
PSF (Point Spread Function) : the PSF, or far field, is the spatial dispersion of the energy in the laser’s focal plane. It is calculated by combining the phase and intensity measurements on the sensor’s surface via the propagation of the electromagnetic field in accordance with the law of free space propagation.
Modulation Transfer Function (MTF): thanks to our patented Shack-Hartmann technology, the MTF is calculated for all directions at the same time. The MTF module also lets you compare your measurement to those of a perfect system. WaveView represents the MTF as a curve, using contrast to indicate the spatial frequency in a given direction.
With just a few clicks you are ready to perform you experiment, follow your measurement in real time right on your screen, save your data, optimize and analyze it by using the PSF and MTF options.
