RoperScientific / Princeton¶
Introduction¶
This plugin control a RoperScientific/Princeton camera under Windows and Linux, using the PVCAM (Photometrics Virtual Camera Access Method) libraries.
It is in production at SOLEIL under windows and it has been tested at Desy under Linux. Model used at SOLEIL: PI-MTE:2048B
Prerequisite¶
The RoperScientific is connected to a specific computer with a PCI board. The Lima/RoperScientific client must run on this PC.
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.
Camera initialisation¶
The camera will be initialized within the :cpp:RoperScientific::Camera
object. The camera number (as an integer) should be given to the constructor. For example: 0.
Std capabilites¶
This plugin has been implemented in respect of the mandatory capabilites but with some limitations according to some programmer’s choices. We only provide here extra information for a better understanding of the capabilities for the RoperScientific camera.
HwDetInfo
Max image size is : 2048 * 2048
16 bit unsigned type is supported
HwSync
Trigger type supported are:
IntTrig
ExtTrigSingle
ExtTrigMult
ExtGate
Optional capabilites¶
HwBin:
all values are accepted
HwRoi
Specific control parameters¶
Some specific paramaters are available within the camera hardware interface. Those parameters should be used carefully and one should refer to the camera SDK (or user’s guide) documentation for a better understanding.
getTemperature()
set/getTemperatureSetPoint()
set/getGain()
set/getInternalAcqMode()
“FOCUS”
“STANDARD”
set/getSpeedTableIndex()
Configuration¶
No Specific hardware configuration are needed
How to use¶
Here is the list of accessible fonctions to configure and use the RoperScientific detector:
void setGain(long);
long getGain();
void setFullFrame(rgn_type* roi);
void setBinRoiParameters(rgn_type* roi);
void setSpeedTableIndex(unsigned);
unsigned getSpeedTableIndex(void);
const std::string& getADCRate(void);
double getTemperature();
double getTemperatureSetPoint();
void setTemperatureSetPoint(double temperature);
Code example in python:
from Lima import RoperScientific
from lima import Core
cam = RoperScientific.Camera(0)
hwint = RoperScientific.Interface(cam)
ct = Core.CtControl(hwint)
acq = ct.acquisition()
# set some configuration
cam.setTemperatureSetPoint(0)
cam.setAdcRate(0) # 0-1MHz, 1-100KHz
# 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.EDF
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(0.1)
lastimg = ct.getStatus().ImageCounters.LastImageReady
# read the first image
im0 = ct.ReadImage(0)
