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. 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. Patents.
