UUTrack.Model.Cameras.Hamamatsu.py

Model class for controlling Hamamatsu cameras via de DCAM-API. At the time of writing this class, little documentation on the DCAM-API was available. Hamamatsu has a different time schedule regardin support of their own API. However, Zhuang’s lab Github repository had a python driver for the Orca camera and with a bit of tinkering things worked out.

DCAM-API relies mostly on setting parameters into the camera. The correct data type of each parameter is not well documented; however it is possible to print all the available properties and work from there. The properties are stored in a filed named params.txt next to the Hamamatsu Driver

Note

When setting the ROI, Hamamatsu only allows to set multiples of 4 for every setting (X,Y and vsize, hsize). This is checked in the function. Changing the ROI cannot be done directly, one first needs to disable it and then re-enable.

class UUTrack.Model.Cameras.Hamamatsu.camera(camera)

Bases: UUTrack.Model.Cameras._skeleton.cameraBase

GetCCDHeight()

Returns The CCD height in pixels

GetCCDWidth()

Returns The CCD width in pixels

acquisitionReady()

Checks if the acquisition in the camera is over.

getAcquisitionMode()

Returns the acquisition mode, either continuous or single shot.

getExposure()

Gets the exposure time of the camera.

getSerialNumber()

Returns the serial number of the camera.

getSize()

Returns the size in pixels of the image being acquired. This is useful for checking the ROI settings.

initializeCamera()

Initializes the camera.

Returns:

readCamera()

Reads the camera

setAcquisitionMode(mode)

Set the readout mode of the camera: Single or continuous. Parameters mode : int One of self.MODE_CONTINUOUS, self.MODE_SINGLE_SHOT

setExposure(exposure)

Sets the exposure of the camera.

setROI(X, Y)

Sets up the ROI. Not all cameras are 0-indexed, so this is an important place to define the proper ROI. X – array type with the coordinates for the ROI X[0], X[1] Y – array type with the coordinates for the ROI Y[0], Y[1]

stopCamera()

Stops the acquisition and closes the connection with the camera.

triggerCamera()

Triggers the camera.
