Intelligent Fiber Optic Systems Corporation, IFOS, is a silicon valley based pioneer of developing advanced sensing systems using fiber optics for the measurement of physical, chemical and biological parameters derived from the interaction of light with matter. Pressures to 1 kBar, temperatures to 1000°C, strains as small as sub micro strain and as large as 10,000 micro-strain and a number of strain derived parameters can be measure very accurately in extreme environments of space, energy exploration and the human body.
