This is a page to track lenslet mask performance issues and the steps we take to troubleshoot. So far the lenslet mask performance has become more unreliable. Due to the lack of encoders, there is no feedback to track which lenslet mask position is really in use. The unreliable behavior has made it more difficult and time consuming to make rectification matrices.
Default lenslet mechanism setting:
speed = 300 steps/s
acceleration = 200 steps/s
homing speed = 400 steps/s
A few things to try to troubleshoot:
- Try reduce speed to 200 steps/s
- Try reduce acceleration
- Try changing om4s homing speed
- Try moving between narrowband and broadband and see if it is reliable
- Check whether scan_number locations are defined correctly
Problematic recmat scan symptoms:
After about 100 scans (in narrowbands) lenslet fluxes drop significantly and become uneven
Uneven lenslet fluxes in every scan
