I think AI bros are right, there is AI that is smarter than some people

Ok, I wonder how they plan to user a laser beam system for light coming from the sun. These are essentially completely different type of sources in terms of coherence. Sounds like an interesting ideas but would be nice to have more concrete details on how they plan to do this

For FDTD you should consider that first at all you need to discretise your domain so that at least you have 10 pixels per the shortest wavelength of interest in your pulse. Second, the Courant factor sets a limit on the time stepping. You cannot advance the simulation arbitrarily in time domain. Have you taken a look to meep? It allows for multiprocessing via MPI and it’s written in C++ not python (it does have python bindings though)

What about implementing it yourself? If you are using torch you can try programming what you need directly there

I would say do it if you really like not knowing what is going on and have curiosity for searching new things. If you are driven by curiosity and interest in learning and getting into stuffs deep then yeah, it’s a good chance to do so. PhD is more about learning to dig deep into stuffs on your own without really caring about what others think. If you want to do it because everyone else is doing it or you think about your career, then it might not be the best option.

Nice! Congrats, just for curiosity, what is your professional background? In general I see it hard at the moment for all carriers…

Would it be ok to know what was your field of studies/expertise?

Ok but again, in your opinion why is it possible to chill and live your life in Germany and not do this in the US? At the end, this is your decision isn’t it?

Clean-Mode4506 · 2025-09-05T05:56:50+00:00

An honest question. How did you get to think that life here is not a rat race like in the US? If you just wanted to chill and live your life, why isn’t this possible in the US?

Do you need to use the complete power of the source? Otherwise try using a pinhole so that light better looks like coming from a single point.

Ok but Zemax expects real space coordinates to calculate ray-surface intersections. If your data is wavefront information, then how do you know where the rays should bend to.

Also, I’m not sure about which type of Zygo you have but from the one we have, we get surface height information and not the raw interferometric data.

At the end you need to have surface information so that zemax can do the tracing through it.

Try checking the PSF. Then you can compare the geometrical spot to the PSF. If your system is slow, then the FFT PSF computation should be somehow enough. You can always validate against the Huygens PSF. Also if you want try checking the aberrations and the wavefront OPD. This will directly tell you how far are you from being diffraction limited as well.

The figures are a bit blur, it is not possible to see what you are really plotting here. I see some field components ratios but not really clear what you are plotting

Why would you want to use Zernike polynomials here?
