Princeton’s camera are often use for Spectroscopy.
This Lima module has been tested with:
Pixis 100 and 400.
This module was tested with PiCam 5.x. You can get it .. _Latest: ftp://ftp.piacton.com/Public/Software/Official/PICam/PICam%20Install.exe
Documentation can be found .. _Doc: https://www.princetoninstruments.com/products/software-family/pi-cam
Installation & Module configuration¶
First, you need to install the SDK.
Then, follow the generic instructions in Build and Install. If using CMake directly, add the following flag:
For the Tango server installation, refers to PyTango Device Server.
Initialisation and Capabilities¶
Implementing a new plugin for new detector is driven by the LIMA framework but the developer has some freedoms to choose which standard and specific features will be made available. This section is supposed to give you the correct information regarding how the camera is exported within the LIMA framework.
The interface will be initialized within the
Interface() constructor takes an optional serial parameter.
If serial parameter is left empty, the plugin will open the first camera founded.
Small example showing possible ways to initialize:
from Lima import Princeton from lima import Core interface = Princeton.Interface()
This plugin has been implemented in respect of the mandatory capabilites but with some limitations which are due to the camera and SDK features. Only restriction on capabilities are documented here.
Only support Bpp16 Images.
No restriction, plugin should offer all trigger mode available for the camera.
How to use¶
This is a python code example for a simple test:
from Lima import Princeton from lima import Core hwint = Princeton.Interface("") ct = Core.CtControl(hwint) acq = ct.acquisition() # set and test an acquisition # # setting new file parameters and autosaving mode saving=ct.saving() pars=saving.getParameters() pars.directory='/buffer/lcb18012/opisg/test_lima' pars.prefix='test1_' pars.suffix='.edf' pars.fileFormat=Core.CtSaving.TIFF pars.savingMode=Core.CtSaving.AutoFrame saving.setParameters(pars) # now ask for 2 sec. exposure and 10 frames acq.setAcqExpoTime(2) acq.setNbImages(10) ct.prepareAcq() ct.startAcq() # wait for last image (#9) ready lastimg = ct.getStatus().ImageCounters.LastImageReady while lastimg !=9: time.sleep(1) lastimg = ct.getStatus().ImageCounters.LastImageReady # read the first image im0 = ct.ReadImage(0)
