摘要： A system for monitoring low dynamic pressures in confined spaces, such system comprising a catheter, a multilayered corrugated membrane of diameter less than 2 mm with a reflective inner layer mounted within said catheter; a set of optical fibers comprising one or more illuminating fibers and two or more detecting fibers which are contained within said catheter and whose ends are set at differing distances from the membrane; an illuminating system coupled to said illuminating fibers; and a detection system coupled to said illuminating fibers.
