rotate reflection camera by 40 degree, realign stuff, put lambda/2 plate in illumination
add reverse-x to the camera parameters
use imagemagick to find the position of the first order in the ft of the holograms
try to figure out rft coordinates
first time that i acquired data with two input polarisations
op1: first time i was next to the system.
towards the end, the system made inconsistent noises and the yellow temp current blinked.

i guess i will have to introduce longer breaks
