Abstract

The idea and, design and realization of fiber Bragg grating multiplexing system is given. Special Bragg gratings with very long and linear side slopes were practically realized. They were tuned for different wavelengths distanced 9nm in each measurement channel. The system was applied for strain control. Special spectrophotometer with linear photodiode array was made. For flexible distributed multiplexing of many sensor channels fiber-optic switches were used.
