System and method for intensity monitoring

摘要

A detection system for monitoring the intensity of a stream of modulated pulses, the system comprising a controller configured to provide a control signal to a component outputting modulated pulses the control signal controlling the level of modulation for each pulse exiting the component and a detector configured to measure the intensity of the pulses in the stream of pulses exiting the component outputting modulated pulses, wherein the detector comprises a gated detector, the controller being configured to send a gating signal to said detector, wherein said gating signal varies the gain of the detector with the control signal, such that pulses with a selected modulation level can be detected.

1. A detection system for monitoring the intensity of a stream of modulated pulses, the detection system comprising:
a pulse modulator configured to output the modulated pulses, comprising an input for receiving a control signal and an output for outputting the modulated pulses; a controller configured to provide the control signal to the pulse modulator, the control signal controlling a level of modulation for each pulse exiting the pulse modulator; and a detector configured to measure the intensity of the pulses in the stream of modulated pulses exiting the pulse modulator; wherein the detector comprises a gated detector, the controller being configured to send a gating signal to said detector; wherein said controller is configured to output the gating signal to vary a gain of the detector with the control signal, wherein the detector detects pulses with a selected modulation level.
