Displacement response, detection limit, and dynamic range of fiber-optic lever sensors

PMMA (polymethyl methacrylate) fiber optic probe as a noncontact liquid level sensor

“…Fiber optic sensors have many applications in various branches of science and engineering, as is evident from a vast range of properties which has been sensed optically, ranging from light intensity, vibration, temperature, pressure, calibration of accelerometers, strain, liquid level, pH, chemical analysis, concentration, density, refractive index of liquids, etc. [1][2][3][4][5][6][7][8].…”

Advanced fiber-optic acoustic sensors

“…Bucaro et al created a compact directional acoustic sensor [40] based on a previous work [41], the microphone, which in turn was based on an earlier reported fiber-lever probe [42]. This sensor is composed of a two-fiber optical probe, an optical source, a photo-detector, and a slender cylindrical cantilever to which an optical reflector is attached, as depicted in Fig.…”

Modeling of a polyimide diaphragm for an optical pulse pressure sensor

“…MEMS diaphragm can be made from polymers by processes such as injection moulding, embossing and stereolithography [10]. Polymer diaphragm has been widely used for a limited detection space as presented in [11][12][13][14][15][16][17][18].…”
