VideoFROG Scan  -- versatile data acquisition, processing, and display

The best test and measurement tools tightly integrate software and hardware.  The software not only must control the hardware, but must provide the user information digested for their unique application.  The user must be able to easily control the measurement process.  In addition, the user must be able, at a glance, assess the complete measurement process.  They must not only understand the measurement, they must trust the measurement.  Am I measuring what I think I’m measuring?  Is the measurement correct?  I’m I measuring what I need to measure?  Is this really what my pulse looks like?  With the summary panel of the of the VideoFROG scan software, those are the questions we want to answer.  Then, we want a clear path to drill down and obtain more information so additional displays and configurations are tabbed with context help for each display and each item--just pass the mouse over the item you want to know more about.

Using popups, you can easily zero in on information most pertinent to the problem at hand.  You can move them to the front, rearrange them, resize them, and minimize them.  Plots provide you with full control of how the results are displayed.  You can display the temporal pulse shape at the same time that you have the pulse spectrum displayed.  You can even zoom in on a temporal region of interest while you are monitoring the spectrum.  Or, you can just simply monitor the pulse statistics.

Measurements are straightforward with the tabbed user interface. Its simple organization allows you to focus only on the information you need at the moment.  The different sections each provide you with a unique view of the operation of your laser--whether it is just pulse width, pulse shape, spectral shape or width, or a view or the FROG trace itself.  Cursors on the pulse display allow data analysis on monitoring on the fly.  A zoom control allows you to select any region of the plot you need to see.
