Redpitaya Forum

Hi,

I have been working on developing a LabVIEW program through which Thorlabs Galvo mirrors can be used to do a raster scan. After a lot of effort and having to create certain library elements for Red Pitaya, I have been able to, programmatically, generate raster scan routines. When hardwired directly, Red Pitaya controls the Galvo mirrors as desired, but, when it comes to LabVIEW, there is a need for Red Pitaya to be able to read the physical channel ID/name of the Thorlabs Galvo controller and then write as commanded to do raster scan in order to complete the feedback loop. I created a subVI for I/O channel communication within the Red Pitaya VI for signal generation, but, it doesn't seem to be working. I have been trying different ways to resolve this but with over-tweaking, there is a possibility of Red Pitaya drivers and library to breakdown so I am being cautious a bit. I don't want to start from scratch again.

Therefore, if anyone has a better solution/idea in order to correctly establish communication between Thorlabs Galvo controller and Red Pitaya (STEMlab 125-14) board through LabVIEW, then can you please help me out here? Any pointers will be of great help.

Thank you for reading the query.

Warm regards,
Arpit

I should clarify that the Thorlabs Galvo mirror control system itself is an open-loop system. I meant to convey the feedback loop of the system as a whole, connection-wise. The scanning system itself is an open-loop system. Thanks to Pavel Demin for pointing it out correctly.
