SmartScan SBI is a complete FBG interrogator offering dynamic measurement of numerous connected FBG sensors from a single board Eurocard format. It has been developed from Smart Fibres’ highly popular SmartScan instrument. This single board instrument is based on an agile, tuneable laser source that enables high resolution interrogation at multi kHz frequencies. It offers connection via a PC 104 interface to a separate processing module required to run software routines to set-up the SBI, read the high-speed FBG wavelength data across the PC 104 bus, and package the received data for processing or onward communication. A suitable PC 104 processing module is available from Smart Fibres, as are drivers for the software routines should a client choose to run them on their own hardware.
Each SmartScan SBI contains an agile electrically tuneable laser, four photo-detector channels, and custom Smart Fibres high-speed gate array electronics for driving the laser and processing the photo-detected signals. The SBI is scalable, and modular systems with multiple SBIs can be assembled to offer 40 nm or 80 nm high-speed interrogation of 4, 8, 12 or 16 fibres. Smart Fibres’ Modular SmartScan is an example of a developed product exploiting this capability.
