Harsh environment applications, such as aerospace and oil extraction, require small, lightweight and robust sensors. The new temperature and strain sensor system presented here consists of a tunable VCSEL, optical circulator, fiber with Bragg gratings at different wavelengths, and pin detectors. It has broad dynamic range, high sensitivity, low weight and a… CONTINUE READING
