Fiber sensing involves using optical effects in fiber Bragg gratings to measure the physical units of strain, vibration, and temperature precisely, in a galvanically isolated manner, and over long distances using interrogators. OCT (Optical coherence tomography) enables high-resolution surface measurements to be made, such as ones for precision engineering, with light of a low coherence length and an interferometer.

Here is a quick overview of the OCT (Optical Coherence Tomograhphy) testers from OCTPRO.
The os1100 Fiber Bragg Grating (FBG) is designed for use in fiber optic sensing applications. It is a single FBG centered in a two meter length of polyimide coated optical fiber. It may be used individually or can be spliced into an array of many FBGs.
The os1200 Fiber Bragg Grating (FBG) Array is designed for use in fiber optic sensing applications. It is a six meter long polyimide coated optical fiber with five FBGs spaced at one meter intervals.
The si155 is an industrial grade fan-less optical sensing interrogator. Featuring both static and dynamic full spectrum analysis, the si155 provides long-term, reliable and accurate measurements of hundreds of sensors on 4 parallel, 160 nm wide channels.
The FBG-based optical sensors offer an alternative to conventional electrical sensors.
The sm125 is a compact, industrial grade, static optical sensor interrogation module, field proven for robust, reliable, and long term field operation.
The os3100 is a spot-welded or epoxy-mounted optical strain gage based on fiber Bragg grating (FBG) technology.
The sm041 Channel Multiplexer is a compact, field proven, industrial grade multiplexer module that conveniently and economically adds measurement channels and fiber connections to an sm125 or sm130 interrogator.
The os3150 is a rugged, spot-weldable strain gage based on fiber Bragg grating (FBG) technology
The os3155 is a rugged optical strain gage with integrated temperature compensation based on fiber Bragg grating (FBG) technology.
The os3200 is a small, non-metallic optical, epoxy-mounted strain gage based on fiber Bragg grating (FBG) technology.
