Researcher in optics and photonics, just hanging around HN because I enjoy both the diversity of the topics and also the way comments are moderated. I can't remember when I discovered HN, but I know I went from /. to digg to reddit them HN. I hope HN will last a bit longer then the others before jumping the shark...

(Scientist chiming in, albeit not working in a relevant field for this discussion) In fact, several well-respected scientists are calling for a scientific and unbiased debate on the origin of covid, as it is now almost impossible for scientists to simply mention lab origin as a possible origin to study. Here is one of the last papers I've seen on this subject:

FYI : I just tried to run it with Playonlinux under linux and it's a semi-victory: it runs, but the pdf rendering window (the main window) is blank...

I just accessed the linked page without any issue, using the latest Firefox... Are you using an old version?

Yes, you can call it a spatially-resolved FTSI, that's correct. There is a whole field of research around FTSI hyperspectral imagers. The big challenge is to get fast enough to get a decent time-resolution.

OK, do you have any reference for the python modules they use? I must admit that for GUI, nice interactive plots, motion control & DAQ, it's a bit difficult to be on par with Labview. In particular, it's usually quite easy and fast in Labview to hack together a small VI to do something like move, grab data, plot, repeat with the ability to zoom, change scale, etc while the acquisition is running. Do you know of any example combining all or part of these functionalities?

If only we could do that! But with ldap accounts, nfs-mounted files and Labview licence server, everything stops working whenever the network is down/unreachable...

We managed to get away from proprietary software for our simulations needs and moved to oss that runs on both Windows and Linux. But we have not been able to get rid of Labview & Windows in the lab. I'll be happy to hear about your experience here...

Well, phosphorescence or fluorescence are basically the same thing: light emission when going from an excited to non-excited state. Many, many materials exhibit some form of light emission when you shine a laser on them, provided that you shine with the right wavelength...
