Abstract: Apparatus for measuring internal pressure within a pressurized container having a deformable wall structure including a stimulus generator for developing oscillatory pressure waves for direction upon a surface of the container, a light source and associated optics for directing a beam of light upon the container surface to develop a reflected light beam, a light detector responsive to the reflected light beam for developing electrical signals commensurate with the surface deflection and an indicator responsive to the electrical signals for indicating a resonant frequency of the container; the resonant frequency providing an indication of the internal pressure within the container.
