Cameras.PrincetonInstruments.PrincetonInstrumentsClass

class Cameras.PrincetonInstruments.PrincetonInstrumentsClass(cameraNumber, triggerMode=0, exposurems=1, gaindB=1, camROI=None, loadDefault=False)

Bases: PylablibInterfaceClass

Parent class for all camera Thorlabs classes using pylablib python driver.

Used as generic driver class if no model-specific child class is defined in same file below

__init__(cameraNumber, triggerMode=0, exposurems=1, gaindB=1, camROI=None, loadDefault=False)

Initialize the Camera object

Parameters:

cameraNumber (int) – index of camera in camerasConfigs list

Keyword Arguments:

• triggerMode=0 (int) – 0 for hardware/external, 1 for software/internal

• exposurems=1. (float) – Exposition duration (exposure) in ms.

• gaindB=0. (float) – hardware gain of the camera in dB.

• camROI=None (None or [int]*4) – Camera region of interest to read from sensor [x offset , y offset , x size , y size ] (binning is not implemented)

• True (loadDefault =) – Decide if default values from cameraConfigs should be set at creation

Returns:

PrincetonInstrumentsClass camera object

Methods

__init__(cameraNumber[, triggerMode, ...])	Initialize the Camera object
clearBuffer()	Clear camera buffer from images.
exposureLevelAutoAdjust([attemptsMax, ...])	Automatic adjustment of exposure for setting image 'Max' or 'Average' to a given level.
grabArray()	Get an image from the camera.
roundCamROI([ROI])	Rounding of ROI values to closest possible one according to camera rules
sendSoftwareTrigger()	Send a software trigger to the camera to start an exposure
setCamROI([ROI])	Set the ROI of camera (without binning)
setExposurems(exposurems)	Set the duration of the exposition
setGaindB(gaindB)	Set the hardware gain of camera readout WARNING : Not Defined for PrincetonInstrumentsClass camera .
setTriggerMode(triggerMode)	Set the trigger mode
startAcquisition()	Start acquisition or restart if already running

__del__()

Delete the Camera object by calling close function

Close the Camera and free memory

sendSoftwareTrigger()

Send a software trigger to the camera to start an exposure

WARNING : No possibility to send a software trigger. If needed, rewrite a grabArray function by starting and stop acquisition with a single frame with internal trigger.

setGaindB(gaindB)

Set the hardware gain of camera readout WARNING : Not Defined for PrincetonInstrumentsClass camera .

Parameters:

gaindB (float) – hardware gain of the camera in dB.

setTriggerMode(triggerMode)

Set the trigger mode

Parameters:

triggerMode (int) – 0 for hardware/external, 1 for software/internal

startAcquisition()

Start acquisition or restart if already running
