METHOD AND APPARATUS FOR IN-SITU DETECTION OF DAMAGE OCCURRING TO AN OPTICAL FIBER OR AN OPTICAL MIRROR

WIPO Patent Application WO/2022/203971

A3

A detector is provided for in-situ detection of damage to an optical fiber, the detector comprising: a laser light detection circuitry disposed at a terminal end of an optical fiber, the fiber coupled to an operating laser pulse generation system, to perform in-situ detection of damage occurring to the fiber, wherein the circuitry is calibrated to detect an energy level of a portion of optical signals sampled from generated laser pulses propagated in the fiber, wherein the circuitry converts the energy of the detected optical signals into electrical signals for processing to monitor a level of the optical signals to indicate normal operational integrity in the fiber or an occurrence of damage to the fiber according to a change in the energy level of the detected optical signals, and outputs a binary signal to a controller to shut off the system within a defined response time if damage is detected.
