Abstract

1,066,354. Interferometric pressure gauge. J. -L. PEUBE. July 8, 1964 [July 8, 1963], No.28179/64. Heading G2J. The differential pressure between two sources is determined by connecting them to tubes e, f, so as to influence the level of the free surface of a liquid m in container a and forming interference fringes between the free surface and a flat strip I supported in the container a As shown light from source g is reflected at h and fringes formed between the reflecting surface of mercury m and transparent strip l are observed at v. A transparent silicone oil i provides damping of the mercury surface. In a modification, Fig.2 (not shown), the liquid employed is a transparent silicone oil and container (a) is filled to a level somewhat above the upper surface of plate (I) which is then formed with a reflective upper surface for forming the fringes. The viewer v may be replaced by a camera or photo-electric counter.
