nlo helps studying the nonlinear optical effects of "frequency doubling" in theory and praxis. For now it provides a graphical user interface to:
1. plot the "maker fringes"
2. capture images from video device.
3. handle Analog/Digital and D/A devices. All obtained data from an e.g. Analog device like an Lock-In Amplifier is visible through genvlin plotter's easy to use LivePlotPanel. You can use pnuts as scripting language in this panel to manipulate existing or calculate new data.
