Bases:
finesse.detectors.general.Detector
,finesse.detectors.general.NoiseDetector
Represents a quantum noise detector with 2 RF demodulations.
It calculates the amplitude spectral density of the photocurrent noise of a photodiode output demodulated at the signal frequency.
- Parameters
name : str
Name of newly created quantum noise detector.
node :
Node
Node to read output from.
f1 : float
First demodulation frequency in Hz
phase1 : float
First demodulation phase in degrees
f2 : float
Second demodulation frequency in Hz
phase2 : float
Second demodulation phase in degrees
nsr : bool, optional
If true, calculate the noise-to-signal ratio rather than the absolute noise value.
sources : list of
Connector
, optionalIf given, only detect quantum noise contributions from these components.
