22 SpectralEye interrogator Spectraleye TM Interrogator - Portable low cost interrogator - ipaq controlled - 90 minutes battery autonomy - RS232 for laptop connection - Window nm - Scan rate 1 Hz - Accuracy 35 pm - sensing > 25 km - No optical experience required

23 Inside the SpectralEye What s inside: - Optical performance monitor - Broadband light source (SLED) - RS232 - USB - Lithium Ion battery - Battery charger

24 system Why a PDA? (HP5550) - Touchscreen control - connectivity (RS232 + USB + WIFI + BLUETOOTH) - Battery - Price

25 Operating system Why embedded C++? - Execution speed - Embedded visual basic was too slow - Object oriented - Low price - Labview PDA was incompetent at that time - Linux incompatible, HP5550 had already Win CE 3.0 installed

26 Layout of the housing - Portable device - PDA needed to be removable (sliding mechanism) - One button launch -Batterypowered - Battery charger for both hardware and PDA - Connectivity panel at the top for both electrical and optical connections - Can be connected to PC without PDA (labview)

27 Software application - list with temperature/strain - temperature/strain in function of time - Optical spectrum (normal/deconvolved)

28 Software application - configuration temperature sensors - configuration strain sensors
