PRESSURE SENSITIVE OPTICAL DEVICE AND PRESENCE DETECTION FLOOR

摘要

The device comprises a series of segments (2a, 2b, 2c) of measurement optical fibre (2) and a series of segments (3a, 3b) of strain fibre (3) extending transversaly to the longitudinal direction of the segments of measurement optical fibre; the segments of strain fibre are alternately arranged on either side of the segments of measurement optical fibre; the fibre segments of at least one series are covered with a protection member (4) providing for a relative displacement of the protection member and the coated fibre segments.
