“…To this end, the detection systems employing a single photodiode (PD) have been designed and applied, among others the bicell and quadrant PDs (two or four PDs separated by a narrow gap). In [3,7], single PDs working in the fiber optic MachZender interferometer configuration have been used.…”

“…The flat diaphragm with two glass optical fibers attached is an important part of the optical fiber sensor construction. Pressure signal on the flat diaphragm allows to detect pressure differences within a wide range of pressure (60Pa -75KPa) and frequency (0.5 Hz -5KHz) [9]. Fig.…”
