Description

Description

This tool plots the geometric size of a coherent source's individual Gaussian beamlets using a specified analysis surface. The functionality is similar to the Positions Spot Diagram except that the Gaussian Ray Size Spot Diagram plots the base ray intersection position as well as the beamlet's 1/e² ellipse.

Application Notes

Why use this tool?

The Gaussian Ray Size Spot Diagram is extremely useful in verifying source definitions, surface beamlet sampling as well as coherent raytracing errors. A common application might be to propagate coherent rays to a surface and use the Gaussian Ray Size Spot Diagram to view the size, shape and density of beamlets with respect to the size of the surface.
