Paper Abstract

Hollow glass micro-spheres, first used to make fibre optic sensors for high hydrostatic pressure, have been interrogated using a high-precision CCD spectrometer, to give far better precision than earlier. It is found that these simple, low-cost micro-sensors have excellent sensitivity to both static and dynamic pressure, and have the advantage of being hermetically sealed. Many other application areas are foreseen for these low-cost sensors.
