	First Claim: Show all 21 claims			What is claimed is: 1. A system for measuring pressure in a vessel having a pressure deformable surface, the system comprising: a light beam emitter means for emitting a coherent light beam impinging directly upon the vessel surface without surface distortion, resulting in a light beam reflected from the vessel surface; a light beam detector spaced relative to the emitter for detecting the light beam reflected from the vessel surface; and, a signal processor means for determining changes in the pressure deformable surface of the vessel as a function of changes in the reflected light beam's position on the detector.
