Abstract
The present invention provides an improved method of manufacturing a pressure transducer of the optical fiber type and an improved pressure transducer of that type, the method including the steps of providing a housing having a greatest interior dimension less than twice the diameter of the optical fibers, deforming the housing by applying pressure thereto such that an interior dimension of the housing along one axis thereof exceeds twice the diameter of the optical fibers, and releasing the pressure on the housing so that the housing substantially resumes its undeformed state and fixedly traps the optical fibers at a preselected location within the housing. An improved pressure transducer of the optical fiber type has a housing receiving the distal end of an optical path, the housing including an aperture, and a pressure sensitive membrane disposed in covering relation to the aperture under tension. The aperture has a substantially nonlinear circumference, preferably in the shape of a circle that was laid on the outer cylindrical surface of the housing as a template for the aperture.
