The value chain for the fiber optic sensors market has been witnessing significant changes as a result of the technological advancements. For instance, the traditional method of manufacturing optical sensors of the Fiber Bragg typically begins with a fully drawn and coated fiber, which must be removed. This is a manual process resulting in the damage to the fiber or diminishing its mechanical stability. Thereafter, at the intended measurement point, the fiber is exposed to ultraviolet laser light. This exposure engenders an interference pattern on the fiber, resulting in periodic areas of high and low refractive index, acting as a wavelength selective mirror. After this process, the fiber is recoated at the exposed locations.
Nowadays, fiber-optic sensors are incorporated with fiber optic amplifiers and easy-to-read digital LEDs. These digital displays offer real-time feedback. Newer sensors demand less wiring; for instance, in a configuration, there must be 16 sensors connected and sharing a single power line. Newer sensors include either a 12-bit or 16-bit CPU along with a 12-bit A/D converter, providing both higher resolution and faster response time. Certain models of sensors allow users remote access. This is especially useful in potentially hazardous environments. By using remote controllers, sensors in a hostile environment can be programmed and monitored from a safe distance.
