ABSTRACT:
An optical coupler (20) is provided for joining first and second opposed fiber optic ends (22, 24). A flexible tubular bladder (30) has first and second opposed ends (32, 34). The first end (32) is sealingly attached to the first fiber optic end (22) and the second end (34) is sealingly attached to the second fiber optic end (24). A light transmissive liquid completely fills a cavity (42) within the bladder (30) enabling transmission of light signals between the first and second fiber optic ends (22, 24). The bladder (30) is deformable to thereby attenuate light signals being transmitted through the light transmissive liquid. This may be achieved by means of a mechanical clamp (46) engageable with the outer peripheral surface of the bladder, by a mechanical iris assembly (52), or by a pressurized atmosphere (FIG. 5 ) applied to selectively reduce the cross sectional area of the cavity to a desired percentage of the initial cross sectional area. This may also be achieved by use of an elongate member (88) wrapped around the outer peripheral surface of the bladder (30) and having opposed ends (90, 92) which can be manipulated to alter the cross sectional area of the cavity. Apparatus using the optical coupler can be used to measure relative movement between a pair of members, as well as a pressure sensor.
