IdealPhotonics' FBG sensor demodulator is a precision instrument specifically designed for analyzing fiber optic grating (FBG) wavelength signals. Through high-speed spectral scanning (resolution ±1 pm) or interferometric demodulation technology (dynamic range > 50 dB), it monitors the center wavelength shift of the FBG reflection/transmission spectrum in real time (sensitivity 0.1 pm). It is suitable for distributed, high-precision sensing systems measuring multiple parameters such as strain, temperature, and pressure."Multi-channel femtometer-level wavelength tracking" utilizes a high-precision interferometer (wavelength resolution 0.1 pm, scan rate 1 kHz) and an intelligent temperature drift compensation algorithm (stability < 0.5 pm/℃) to achieve simultaneous demodulation of 256 channels (dynamic strain resolution 0.1 με). This provides real-time, laboratory-grade measurement performance for large-scale distributed sensor networks such as aircraft load monitoring and smart grids.
