Android Fresnel / Fraunhofer Diffraction

Enter wavelength, aperture and propagation distance on Android to calculate the normalized diffraction pattern.

Learn how to use WaveRay for Android Fresnel / Fraunhofer Diffraction with real, manually matched screenshots. This tutorial covers setup, execution, result interpretation and practical checks.

What this tutorial covers

Enter wavelength, aperture and propagation distance on Android to calculate the normalized diffraction pattern.

Before you start：You need access to the product and should ideally follow the tutorial using your own real parameters or data. The screenshots below were manually rematched to avoid the image/topic mismatches seen in the previous version.

Step-by-step workflow

1Open the module

Open Fresnel / Fraunhofer Diffraction from Diffraction & Wave Optics. Confirm that the visible page really matches the tutorial topic before changing any settings.

2Configure the input

Prepare and check wavelength, aperture, propagation distance and the model options.

3Run and watch the status

Fill in the parameters and recalculate the pattern. Watch the visible status, plot or log area while the workflow is running.

4Inspect the result

Pay special attention to the normalized diffraction curve together with its plotted range.

5Verify and iterate

Change one parameter at a time when comparing patterns so the trend is easy to interpret. Change one meaningful parameter and rerun so you can verify whether the output changes in the expected direction.

How to read the result

  • The main output of this workflow is the normalized diffraction curve together with its plotted range.
  • Read the result together with the exact inputs used for the run; a screenshot alone rarely tells the whole story.
  • Change one parameter at a time when comparing patterns so the trend is easy to interpret.

Troubleshooting & practical tips

  • If nothing changes, first confirm that the correct module is open.
  • If the output looks unrealistic, check units, field mapping and input scale first.
  • For comparisons, change one key parameter at a time whenever possible.
