openUC2 Ptychography

Tutorial

  • Open the terminal
  • Type
cd ~/PTYCHOGRAPHY
sudo python3 01_CameraSerial_XY_v3.py
  • Password is youseetoo

Images are getting saved in the folder PTYCHOGRAPHY -> subfolder according to the time-stamp.-

General Remarks

STop the current programm: CTRl+c

Install and run QV4L2

 sudo apt-get install -y qv4l2

open the live-stream camera by typing qv4l2 and hit enter

this is just a viewer only - no settings are transfered to the ptychographic code! Good for aligning the beam

list cameras with v4l2-ctl -d /dev/video0 --list-formats

Available Camera Parameters

Entering the command v4l2-ctl -d /dev/video0 --list-ctrls follows in:
