Fundamental Diffraction Effects

Diffraction is a very representative phenomenon that shows the wave nature of light. It explains the behavior of light in the region of a geometric shadow. To take diffraction into consideration is often of concern in modern optics, which is beyond the scope of a pure geometric optics approach. We demonstrate two typical fundamental effects in VirtualLab Fusion: the diffraction caused by aperture truncation and the diffraction due to wavefront aberration.

Diffraction Patterns behind Different Apertures

With the advanced propagation technology in VirtualLab Fusion, we calculate the diffraction pattern for apertures with different shapes and study the property of diffraction.

Focal Spots for Different Aberrations

Several typical wavefront aberrations are selected as examples, and their corresponding focal spots are investigated with varying parameters.
