    Diffraction Lenses
AI Thread Summary
Luneburg lenses function by bending light through a gradient index of refraction, allowing for unique focusing capabilities. There are concerns regarding losses due to diffraction and spill-over, which can affect image clarity. Users have shared resources, including animations and PDFs, to illustrate the lens's functionality and provide deeper insights. Focusing a single image with a Luneburg lens is possible, but understanding the optics is crucial for optimal results. Overall, the discussion emphasizes the need for clear explanations and visual aids to grasp the complexities of Luneburg lenses.

Hi there!

I wonder if anyone could explain to me exactly how the optics of Luneburg lenses work? Are there any major losses due to diffraction, spill-over etc? Is it possible to focus just one image using this lens?

Thanks,

Jean

Yes, I knew that. Was just wondering whether anyone could explain it in a few simple words.

Thanks anyway though!

Thanks!
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
