microscope package¶
- class microscope.AxisLimits(lower: float, upper: float)[source]¶
Bases:
tupleLimits of a
microscope.abc.StageAxis.
- class microscope.Binning(h: int, v: int)[source]¶
Bases:
tupleA tuple containing parameters for horizontal and vertical binning.
- exception microscope.DeviceError[source]¶
Bases:
MicroscopeErrorRaised when there is an issue controlling a device.
This exception is raised when there is an issue with controlling the device, be it with its programming interface or with the physical hardware. It is most common when commands to the device fail or return something unexpected.
Note
The subclasses DisabledDeviceError, IncompatibleStateError, InitialiseError, and UnsupportedFeatureError provide more fine grained exceptions.
- exception microscope.DisabledDeviceError[source]¶
Bases:
IncompatibleStateErrorRaised when an operation requires an enabled device but the device is disabled.
- exception microscope.IncompatibleStateError[source]¶
Bases:
DeviceErrorRaised when an operation is incompatible with the current device state.
This exception is raised when the device is in a state incompatible with an attempted operation, e.g., calling
triggeron a device that is set for hardware triggers. The subclass DisabledDeviceError provides an exception specific to the case where the issue is the device being disabled.Note
This exception is for attempting to perform some action but device is wrong state. If the issue is about a setting that is incompatible with some other setting that this specific device does not support, then UnsupportedFeatureError should be raised.
- exception microscope.InitialiseError[source]¶
Bases:
DeviceErrorRaised when a device fails to initialise.
This exception is raised when there is a failure connecting to a device, typically because the device is not connected, or the serial number or port address is incorrect.
- exception microscope.LibraryLoadError[source]¶
Bases:
MicroscopeErrorRaised when the loading and initialisation of a device library fails.
This exception is raised when a shared library or DLL fails to load, typically because the required library is not found or is missing some required symbol.
If there is a module that is a straight wrapper to the C library (there should be one on the microscope._wrappers package) then this exception can easily be used chained with the exception that originated it like so:
.. code-block:: python
- try:
import microscope._wrappers.libname
- except Exception as e:
raise microscope.LibraryLoadError(e) from e
- exception microscope.MicroscopeError[source]¶
Bases:
ExceptionBase class for Python Microscope exceptions.
- class microscope.ROI(left: int, top: int, width: int, height: int)[source]¶
Bases:
tupleA tuple that defines a region of interest.
This rectangle format completely defines the ROI without reference to the sensor geometry.
- class microscope.TriggerMode(value)[source]¶
Bases:
EnumMode of a trigger for a
microscope.abc.TriggerTargetMixin.The trigger mode defines what type of action when a trigger is received, as opposed to the trigger type which defines what constitutes a trigger. The exact type of action is highly dependent on device type, so check their documentation.
TriggerMode.ONCEAct once. For example, acquire a single image when a camera is triggered.
TriggerMode.BULBAct while device is being triggered. For example, a laser keeps emitting emit light or a camera keeps exposing while the trigger line is high. This trigger mode is incompatible with
TriggerType.SOFTWARE.TriggerMode.STROBEAct repeatably while device is being triggered. For example, a camera keep acquiring multiple images while the trigger line is high.
- BULB = 2¶
- ONCE = 1¶
- START = 4¶
- STROBE = 3¶
- class microscope.TriggerType(value)[source]¶
Bases:
EnumType of a trigger for a
microscope.abc.TriggerTargetMixin.The trigger type defines what constitutes a trigger, as opposed to the trigger mode which defines a type of action when the trigger is received.
TriggerType.SOFTWAREwhen
microscope.abc.TriggerTargetMixin.trigger()is calledTriggerType.RISING_EDGEwhen level changes to high
TriggerType.FALLING_EDGEwhen level changes to low
- FALLING_EDGE = 2¶
- HIGH = 1¶
- LOW = 2¶
- PULSE = 3¶
- RISING_EDGE = 1¶
- SOFTWARE = 0¶
- exception microscope.UnsupportedFeatureError[source]¶
Bases:
DeviceErrorRaised when some operation requires a feature that is not supported.
This exception is raised when an operation requires some feature that is not supported, either because the physical device does not provide it, or Python Microscope has not yet implemented it. For example, most devices do not support all trigger modes.
