# finesse.detectors¶

The detectors sub-module contains various non-physical detectors that can be used to probe to simulation at any point.

Listed below are all the sub-modules within detectors with brief descriptions of what is contained in each.

 finesse.detectors.amplitude_detector Single-frequency amplitude and phase detector. finesse.detectors.bpdetector finesse.detectors.camera Detectors for capturing images, slices and single pixels of a beam. finesse.detectors.cavity_detector finesse.detectors.compute finesse.detectors.general Top-level objects which specific detectors should inherit from. finesse.detectors.gouy Accumulated Gouy phase detector. finesse.detectors.knmdetector Direct probing of coupling coefficients. finesse.detectors.motion_detector Motion amplitude and phase detector. finesse.detectors.powerdetector Computes the laser power in an interferometer output or the power from an electrical signal. finesse.detectors.quantum_noise_detector Photodiode quantum noise detector.
