Research Overview
Technical Advances Encourage Adoption in Various Fields
Photonic sensors, signal processors, and communication technologies continue to make headway as viable alternatives to electronics. Fiber optic
sensors have advanced to an extent that they can readily find many applications in manufacturing and detection segments. Recent innovations in fiber
optic instruments and their cost advantages have boosted their utility and demand in several sectors. Environmental and atmospheric monitoring,
industrial chemical processing and biotechnology, as well as defense and security are some of the areas that find use for optic sensors.
This Technical Insights study examines the optical sensors market. It highlights recent technical advances achieved in the different types of fiber
optic sensors, components used in optical fiber sensing, sensor design and analysis, distributed sensing scenarios, and the role of integrated optics
in sensing.
Exciting New Devices Find Application in Diverse Markets
"The optical sensing area is a field in which new technologies are being developed and tested continuously," states the analyst. A
variety of emerging and exciting uses for optical sensors includes predicting ozone contamination and forecasting severe lightning storms. With
increasing emphasis on safeguarding the environment, optical sensors are being employed to measure pollutant levels and contamination in the
environment in real time. "Scientists are also working on the application of the technology in microbial ecology as well as in veterinary and
human clinical diagnostics," remarks the analyst.
The U.S. Navy's Sensors Branch investigates new applications such as precise time and position determination, environmental characterization, and
surveillance. Health monitoring sectors have also cashed in on the developments in optical fiber sensors as they offer the advantages of low cost,
amenability to multiplexing, and high sensitivity over conventional systems. Numerous optical sensors under development include chemical, temperature,
laser, strain, electric, and magnetic sensors. Vertical and edge-emitting semiconductor laser diodes and arrays are also being researched for further
improvements.
Several Industries to Benefit from Use of Optic Sensors
Some industries that will benefit from optical sensors include certain processing industries that can use sensors for controlling chemical
formulations and temperatures. In the medical industry, the sensors will facilitate the development of novel imaging systems. The sensors will help
the construction industry monitor the structural health of different buildings, bridges, and tunnels and facilitate the environmental industry in
monitoring pollutants and contamination.
"The multiplexing capability of optical sensors makes them an excellent candidate for structural health monitoring in aerospace applications
where weight is a major consideration," notes the analyst. Degradable polymer sensors are used to deliver antiviral drugs, pain and chemotherapy
medications, and contraceptives. Universities and companies can use simulation equipment for their research and teaching needs. A range of basic and
applied research programs are being conducted in aeropropulsion, space sciences, photonics, and materials technology.
