Hello,

This post would just like to share how you could find stray light with OpticStudio hologram model.

In the following knowledge base article,

Simulating diffraction efficiency of a volume holographic grating using Kogelnik’s method

we have shared an non-sequential example as below.

It's not obvious, but here are actually some stray light in this example. To find them, we can just increase the Contrast Enhancement in Detector Viewer as shown below.

Then you can find those 0th order ghost!
