Simulate you own mask diffraction pattern

You can load any type of mask and simulate the diffraction pattern for any wavelength.

Download “Maskulator” here: Maskulator (7365)
Version 5.0, July 18 2009

Updates will follow. Planned features are:

- full color spectrum in one image DONE in V2.0
- save as AVI DONE in V3.0 sample AVI here, divx codec used
dowload DivX codec here
- save as bitmap DONE in V3.0
- V4.0 bug fixes in number of frames
- V5.0: write AVI compressed in codec of choice

    Beste Niels,

    Is het mogelijk om van dit handige programma een Linux versie te maken? Ik kan hier waarschijnlijk wel bij helpen, heb enige ervaring met Pascal en C (Java zal het wel niet zijn).

    Alvast bedankt voor je antwoord!
    Pieter

    Hi Niels,

    I am the author from telescope design software MODAS and the editor of ATM Letters Journal. Today by searching in the web I found your stuff about Bahtinov masks and software fresnel.exe. I wish to publish in my short review about this program, but I’m not sure who is the owner of the software, here is no program about or readme file. Can you contact me?

    Thanks in advance!

    best regards

    Ivan

    The program does not work here. Windows server 2008, 64 bit.
    Loading a mask works. Nothing else.
    When I click “calculate” the picture disappears and that’s it.
    If I click save BMP or AVi – and error message appears (unhandled exception)

    You need the 64-bit version dll of fftw:
    Download here.
    Unzip to your folder that keeps maskulator and you are set to go.

    Yes, it works now. Thanks ! The libfftw3f-3.dll was overwritten but I guess that’s normal. Just to let other people know.

    Is it possible to add phase-mask options to Maskulator?

    Yes, let me know what you need/want.

    I’d like to load 2 mask. First one for amplitude distribution and second for phase distribution. It’s a general form of Bahtinov mask.
