Abstract
The dual wavelength fibre optic perimeter sensor bases on
input signals measurements in an arrangement of fibre optic Michelson and
Sagnac interferometers with a 3 
3 coupler and two semiconductor
lasers. For 3 km long sensor we obtained 20-50m resolution of determination
of disturbance point.
