Code for use in lab environment: experiment automation, data acquisition, device communication
PyLabLib aims to provide support for device control and experiment automation. It interfaces with lots of different of devices, including several different camera interfaces, translational stages, oscilloscopes, AWGs, sensors, and more. The interface is implemented in a natural way through Python objects, and is easy to understand. For example, here is a complete script which steps Thorlabs KDC101 stage by 10000 steps ten times, and each time grabs a frame with Andor iXon camera:
from pylablib.devices import Thorlabs, Andor # import the device libraries import numpy as np # import numpy for saving # connect to the devices with Thorlabs.KinesisMotor("27000000") as stage, Andor.AndorSDK2Camera() as cam: # change some camera parameters cam.set_exposure(50E-3) cam.set_roi(0, 128, 0, 128, hbin=2, vbin=2) # start the stepping loop images =  for _ in range(10): stage.move_by(10000) # initiate a move stage.wait_move() # wait until it's done img = cam.snap() # grab a single frame images.append(img) np.array(images).astype("<u2").tofile("frames.bin") # save frames as raw binary
The list of the devices is constantly expanding.
Additional utilities are added to simplify data acquisition, storage, and processing:
Assorted functions for dealing with file system (creating, moving and removing folders, zipping/unzipping, path normalization), network (simplified interface for client and server sockets), strings (conversion of various Python objects to and from string), and more.
Python 3 (tested with 3.6+)
Most extensively tested with Windows 10 and 64-bit Python. Linux is, in principle, supported, but devices which require manufacturer-provided DLLs (mostly cameras) might, potentially, have problems.
Some devices might require additional software. If this is the case, the requirements are mentioned on the corresponding page.
You can install the library from PyPi:
pip install pylablib
More options are described in the documentation.
