Interferometric force measuring device

摘要

The invention is based on the object of providing a device for measuring small forces, which cannot be adversely affected by electromagnetic and electrical disturbing fields. According to the invention, the object is achieved in that a deformation body is used, which consists of a bending body and of an inflexible base body, and that a weighing beam is arranged on the bending body. Connected to the deformation body are the assemblies of an interferometer specially suited for being supplied with monochromatic radiation by means of optical waveguides and for scanning the interference phenomenon, likewise by means of optical waveguides. By means of suitable fastening of the assemblies on the deformation body, using distance rings, the influences as a result of temperature changes are eliminated. <IMAGE>
