POF/LS3
Light State Sensor
System, OSV
This sensor uses plastic optical fiber (POF) to inexpensively capture phenomena occurring at the tip of the optical fiber.
It is used for mortar filling detection, etc.
Please refer to technical information.

Sensor Net powered by Fiber-optic
Sensor Network powered
by Fiber Optic
This is unique sensor network system.
Sensor unit is activated locally by laser power, which is transmitted thorough normal fiber optic network. So no local power supply is necessary, just optical fiber.
Any sensor is connectable, preferrably low-power-consumption sensor, such as MEMS.
AE Log and Analysis software
Software for AE logging and off-line analysis.
This program is based on LabVIEW, provided National Instruments Japan.
Software has :
– AE logging
– Re-calculate AE parameter
– Reat out waveform
As an option, source location software is also available.
FBG sensor
We provide FBG sensor both coated by UV acrylate and polyimide for WDM methods.
