Free diffraction software for mac

Diffraction is an important physical effect inherent in all wave phenomena. Fraunhofer and Fresnel diffraction are two important classes of diffraction. Fraunhofer diffraction involves coherent plane waves incident upon an obstruction. Fresnel diffraction is the same, except that the waves are spherical, effectively originating from a point source.
Fresnel Diffraction Explorer is based on an efficient algorithm to calculate numerically a Fresnel diffraction pattern using any two-dimensional aperture.
It is a simple exercise to show that Fraunhofer diffraction by an aperture is mathematically equivalent to the Fourier transform of the aperture shape. Because the integrals describing Fresnel diffraction are so intractable, however, Fresnel diffraction patterns have few analytical solutions, even in one dimension. ... A calculation in two dimensions is even more problematic.
Enhancements:
Universal Application release for Intel- and PowerPC-based Macs running OS X. Clusters of any combination of Intel or PowerPC Macs can be used in a Fresnel diffraction calculation.
Other updates:
- OS X-compliant icons, dialog boxes, including sheets and antialiased text.
- Endian conversion for file and disk storage as well as sending data over the network.
- Adaptations to bundle formats and Xcode.
- When using multiple wavelengths, FDE can export to QuickTime in addition to PICS.
- Establishment of a data fork only file format.

Enhancements: Includes many new features for both unregistered users and CSD System subscribers. The unregistered mode of Mercury has been updated to include features previously only available to licensed CSD System customers, such as:

• A Style Manager that allows easy creation of different visual styles
• An improved Structure Navigator
• Improved customisation options
• New file reading and output options
• Greater control over atom labelling
• Display of thermal ellipsoids and symmetry elements
• The ability to calculate graph sets
• The ability to view structures in stereo (with appropriate hardware)
• An interface to MOPAC

Requirements: Mac OS X 10.4 or later.

OpticsCalcX 2.0.3 is considered as a superior and simple to use calculator program for everyone from students to engineers who know optical theory, but need a quick and efficient way to perform the calculations. It frees your mind from having to remember all the equations, and lets you concentrate on solving the problem at hand!

With OpticsCalc, just select the type of calculation and parameters, and enter the known value(s). It does the calculations for you - and you can even copy and paste the results into another document.
