A simple extrinsic optical-fiber strain sensor that uses a thin transparent
elastic polymer film acting as a low-finesse Fabry-Perot interferometer ha
s been developed and tested. The polymer is mounted at the end of a multi-m
ode optical fiber as a strain sensitive element. The strain resolution of t
he sensor is 2 x 10(-6), the accuracy is 5 x 10(-6) over dynamic range 0-50
00 x 10(-6). (C) 2001 Elsevier Science B.V. All rights reserved.
