New paper on #ArXiv!
When (coherent) light propagates in a multimode fibre, each mode accumulates a slightly different phase, so the output looks like a random speckle patter.
But it is NOT random!
This non-randomness has a number of consequences, among them the fact that the you get predictable patterns in the apparently random output. We show that a focused input will always result in a ring of excess intensity at the same radius of the input (and suggest how this might be useful).

This is sickening

#Trump's Military Audience While in Uniform Were Checked for Allegiance

“Internal 82nd Airborne Division communications reviewed by Military.com reveal a tightly orchestrated effort to #curate the #optics of Trump's recent visit, including HANDPICKING SOLDIERS for the audience based on #political leanings & physical appearance.

One unit-level message bluntly saying: "No fat soldiers."

Please share: Our Max Planck Institute recently left X and is present here on Mastodon. Give them a follow! Beautiful pictures from the science of light!
