Positional feedback

[dwgong]

Dear developer, is it true that the current package only takes care of the intensity for each spot during camera feedback but not the position? Do you have an intention to implement such function? Thanks for your time! I would be happy to discuss this idea with you since our group is also thinking about it.

Hi @dwgong ,

This is already implemented as SpotHologram.refine_offset(). Usually this needs a few iterations to hone the positions, so you can either call it between instances of the optimize() loop or as part of a callback= function to optimize(). Let us know if this is what you're looking for! You're correct that this function is a bit hidden, so we'll add it to the examples in the next release.

Best,
Ian

(This is not enabled by default in the way that intensity weighting is because of the chance of unusual behavior, esp. if the spots are reflected off of patterned substrates.)

lol I see, thanks a lot! I'll try and play with it.
