PRODUCT UPDATE
Sensors and detectors Fibre strain sensor
AMS Technologies has introduced a polymer optical fibre (POF)-based strain sensor solution for industrial applications.
Based on a patented optical phase interrogation (OPI) technique, the solution enables the POF to be used as a high-precision strain
PixelSensor developer board
Pixelteq has introduced a multispectral sensor developer board that helps OEMs design and prototype optical sensors based on its PixelSensor wavelength-selective photodiode arrays.
PixelSensor’s wafer-level optical filters simplify optical designs and enable OEMs to implement precision multispectral measurement in smaller devices. Designers can choose board and accessory options that help them get started with spectral sensing in minutes for a wide range

of biomedical, industrial and scientific applications. The PixelSensor developer board includes the essential hardware and a cross-platform GUI interface to configure measurement settings of each spectral band individually, trigger external functions, communicate with other devices, and display and log data. In addition to comprehensive sensor evaluation, designers can program application-specific functions using the Arduino integrated development environment.

sensor on par with current fibre Bragg grating (FBG)-based strain sensors. Applications include wind-blade load management in wind turbines and structural health monitoring for other structures.
The optical sensor employs the POF to form a ‘meander path’ sensor array that allows a single fibre to form
multiple loops that fit in a confined area. When strained, these loops will alter the phase of an optical signal injected into the fibre.
A separate reference loop that is not strained surrounds the meander path and is used to compare the reference signal to the strained signal, and the difference in phase between
the two signals can be converted into the strain measurement.
