**3.3 Laboratory experimentation module**

One of the most interesting features of the tool is the possibility to compare simulations with real experiments. Fig. 3 shows the basic laboratory setup. A collimated He-Ne laser illuminates the object (aperture), and the corresponding diffraction pattern projected on the output screen is stored by a video camera.

Images captured by the video camera can be stored and processed by the laboratory experiment module shown in Fig. 4.
