A small-size, high-precision fiber Bragg grating interrogator was developed for continuous plethysmograph monitoring. The interrogator employs optical edge filters, which were integrated with a broad-band light source and photodetector to demodulate the Bragg wavelength shift. It can run on batteries or be plugged into an external power source, and is supplied with an easily. BaySpec's WaveCapture™ fiber Bragg grating interrogation analyzers (FBGA) are revolutionizing the fiber sensing world offering, for the first time, excellent wavelength accuracy, ultra-low power consumption, small form factor, fast (sub-ms) response time, no moving parts, and lifetime calibration. Integrated spectral analyzer with an internal reference source (IRS) that serves as the heart of precise, fast, and reliable FBG sensing systems requiring increased precision. This is because FBG technology has advantages such as multi sensors in a single optical fiber, overall lightweight passive design, and low. This state-of-the-art FBG interrogator can monitor and measure changes in pressure, tilt, cracks, position, tension, bolt elongation, displacement, linear and rotary movement.
