发明名称 Gauge for measuring high transient pressures
摘要 An article and method is provided for remotely optically measuring high transient isotropic pressures. The arrangement employs a fluorescent crystal (such as a ruby) secured to one end of an elongate optical fiber waveguide for placement in the vicinity of a high pressure occurrence such as near an explosion. Light launched into the free end of the waveguide travels the length thereof to stimulate the crystal, which in the case of a ruby, fluoresces in the red, the wave length of which varies in response to isotropic pressure on the ruby. This red light output is transported back along the same optical fiber waveguide to the free end where its wavelength change is monitored and translated into a pressure value on the crystal.
