Fiber Optic Sensor Systems

Techno-Sciences has been involved in several instrumentation projects that
have required the use of fiber optic sensors and optical signal processing
since the late nineties. Over this period the personnel have acquired
expertise in working with fiber optic sensors. Some of these are detailed
below:

Core Expertise/Experience:

• Design and fabrication of ratiometric and wavelength division
  multiplexing (WDM) sensor demodulation systems in the 1550nm and 1310nm wavelength regimes
• Optical filtering implementation using linear sloped, notched, and chirped tunable filters
• Implementation of optical muzzle reference, velocity measurement,
  distributed sensing, and health monitoring systems on military platforms
• Hoop strain diagnostics and analysis with optical sensors on medium caliber gun systems
• Optical signal processing and opto-electronic hardware design,
  prototyping, and fabrication
• Structure health monitoring using Fiber Bragg Grating sensors
• Strain event time stamping
