Home / Working principle of fiber optic barometric pressure sensor
The core principle of fibre-optic pressure sensors lies in the modulation and demodulation of optical signals. Compared with conventional sensing technologies, FOS demonstrates superior capabilities in. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time.
Light from a source is transmitted through an optical fiber to the sensing element. The sensing element modifies the light signal in response to the applied pressure. The modified light signal is then
