Can the sensing distance of a fiber optic sensor be adjusted

Fiber Optic Sensor

Distributed sensors are able to sense at any point along a single fiber line, typically every meter over many kilometers of length.

Fiber-optic sensor

The efficiency of fiber Bragg grating based fiber-optic sensors can be provided by means of central wavelength adjustment of light emitting source in accordance with the current Bragg gratings

Target detection is based on the amount of reflected light returned to the receiver. Because the detecting distances range from a couple inches to several meters, adjustment during installation is incredibly
