labscript_imaging

This is our basic (prototype) integration of our cameras ORCA-Flash4.0 V3 Digital CMOS camera C13440-20CU, pco.edge 4.2 LT and Flir Chameleon 3 (former Point Grey) into labscript for absorption imaging.

Notes

• The device implementation consists of a two parts in a client-server architecture:
  • The labscript device 'camera.py', is placed in the folder 'labscript_suite/labscript_devices' and then imported in the labscript file as well as in the connection table
  • The independent worker 'camera_server.py' is to be run from command line (e.g. anaconda prompt) in python 2.7 and manages the communication with the specific device. In this way running a different python version and running it on a different machine is possible.
• This labscript device is written for an old version of labscript in python 2.7 (should be hopefully easily portable to python 3)

Example

Labscript File:

""" Import labscript device """
from labscript_devices.Camera import Camera
...
Camera(name = 'PCOEDGE', 
         parent_device = docard,
         connection = 'port2/line2',
         BIAS_port = 77,
         exposure_time = expose_t)
...
""" Take a picture """
    PCOEDGE.expose(name = 'test_pic', t = t, frametype = 'test')

Connection Table:

""" Import labscript device """
from labscript_devices.Camera import Camera
...
Camera(name = 'PCOEDGE', 
         parent_device = docard,
         connection = 'port2/line2',
         BIAS_port = 77,
         exposure_time = expose_t)
