Abstract

We present a new kind of compact, simple, and low cost optical pressure sensor. The physical principle on which the sensor is based, components, layout of the system, and characterization are described. The range of pressures in which the sensor works is from about 0.5 to 3 psi (1โ€‰ psi=6.895โ€‰kPa).
