SmartScan is an ultra-compact and robust interrogator for dynamic measurement of FBG sensors. This WDM instrument is based on an agile, tuneable laser source that enables high resolution interrogation at multi kHz frequencies. The high frequency scan rates allow over-sampling and averaging to give extraordinary resolution.
Data can be written to an Ethernet or other industrial bus interface, or saved to a connected USB device.
Our suite of applications supplied free of charge with every interrogation system
A Complete Single Board FBG Interrogator offering SmartScan performance on an OEM module suitable for client integration.
A miniaturised SmartScan suitable for aerospace flight or other harsh environment applications.
A 19" rack variant of SmartScan offering up to 16 channels and an 80 nm wavelength range for large sensor network interrogation.
Optical fibre fatigue reliability is very high and FBG sensors benefit from this fact. For instance, client tests found that Smart Fibres’ SmartPatch sensors were still 100 % functional after 6 x107 cycles of tensile and compressive fatigue loading.
All of our fibre optic sensors come with a standard one year warranty. This warranty can be increased on a year by year basis. Extended warranty is available at the time of initial purchase on request.

Smart Fibres has created a wavelength budget calculation tool for FBG wavelength selection.

Yes, the scan rate is user definable in the SmartSoft software. Table below gives an indication of the scan rates available:
(All channels simultaneously)
Our instruments have a dynamic range of 27 dB optical power. The table below gives a rough estimate of each device’s loss.
When using low reflectivity FBGs such as drawtower gratings the optical power budget is reduced from 27 dB to 11 dB.
1 x 2 coupler
1 x 4 coupler
1 x 8 coupler
The algorithm embedded in the SmartScan needs a several laser tuning points to overlap the reflection shape of the FBG. In order to achieve a non-linearity error compatible with the SmartScan Specifications, we recommend to use FBG with an FWHM between 0.5 and 1 nm.
Narrower FBGs can be used, at the expense of reduced linearity.

All of our interrogators are supplied with our standard SmartSoft suite of LabVIEW based applications.

Generally speaking the faster the processor speed and the newer the processor technology the more likely it is to cope with the speed of data. Nearly all new off-the-shelf laptops and desktops would be fast enough, and these typically have an i3 with a processor speed of 2 GHz or better. Older desktops with Intel Duo ~3 GHz processors are also fast enough.
Yes, any SmartScan interrogator can initially be configured with a PC and then disconnected to log the measurement data to a USB solid state storage device or, in the case of SmartScan Aero Mini, it's onboard flash memory.
Three parameters are needed to calculate the length of data that can be stored: disk size, acquisition rate and number of FBG.
For SmartScan USB data is stored in a raw format.
For 32 FBGs at 2,500 Hz, 100 minutes of data can be stored per GByte of disk space; this can be scaled proportionally to number of FBGs or acquisition rate.
E.g., for 16 FBGs at 2,500 Hz, 200 minutes / GByte
E.g., for 32 FBGs at 500 Hz, 500 minutes / GByte
E.g., for 16 FBGs at 250 Hz, 2,000 minutes / GByte
For SmartScope, data would likely be processed into measurement units, so it would be in the same format as files saved by SmartSoft, in which case each measurement uses 10 bytes, plus 10 bytes for the timestamp.
E.g., 32 FBGs = 330 bytes per sample
E.g., 16 FBGs = 170 bytes per sample
E.g., 1 FBG = 20 bytes per sample
E.g., 32 FBGs at 5 Hz = 10,000 minutes / GByte
E.g., 16 FBGs at 5 Hz = 20,000 minutes / GByte
E.g., 32 FBGs at 1 Hz = 50,000 minutes / GByte
E.g., 1 FBG at 1 Hz = 800,000 minutes / GByte or about 18 months / GByte
SmartScan can synchronise to a NTP time signal via its Ethernet port.
In this scenario SmartScan would need to be connected on a Local Area Network (LAN) and would also need to be able to access an NTP server, either on the same LAN or over the Internet.
All the data from SmartScan is time stamped, so if an NTP signal is received the timestamps would be synchronised to that signal. See “Plug-in for NTP synchronisation” in the SmartSoft user manual.
All data from SmartScan is transmitted with a Universal Time Coordinated (UTC) time stamp. The SmartScan’s UTC time is synchronised with the host PC’s clock every time SmartSoft connects to the interrogator. Therefore SmartScan data can be synchronised with time stamped data from other measurement systems.
No on-board averaging is done. Averaging is done in SmartSoft on the PC connected to the instrument.
Yes, SmartSoft software has the functionality for the user to set both the scan rate and averaging rate. This will reduce the number of data points being logged to file.
For data transmission we can offer Ethernet, CANopen, Modbus/TCP, Modbus/RTU and Profibus DP but not all are available on all our interrogator models.
Please note that some communications protocols will limit the acquisition rates of the instrument, e.g., CANopen is up to 250Hz.
No, the RS232 port is only used for diagnostics connection.
