    Abstract: A reflecting assembly for polarized white light includes at least one mirror associated with a birefringent compensator preventing the reflected light from having a large phase anisotropy. The mirror or mirrors are metallic and covered with a protective silica layer having a geometric thickness of from 0 to about 400A. The birefringent compensator is a crystalline plate of predetermined thickness depending upon the thickness of the protective layer. Known compensators may be used in place of the birefringent plate.

    Abstract: An apparatus for providing electrical signals representative of relative movement between two members includes a source of radiant energy conveniently light. A movement sensor fixed to one of the movable members comprises at least one detector responsive to energy from the source. A graduated track fixed to the other movable member is composed of a regular alternating series of marks and spaces capable of varying differently the energy from the source which is received by the detector by way of the track. Thus each detector provides a periodic undulating signal as the two members move relatively to one another. The or each signal is transformed by a reshaping device in which it is compared with a reference signal derived from at least one other detector exposed to energy from the source to derive a rectangular signal varying between one and the other of two logic levels. The reference signal may be derived by combining signals from two or more detectors exposed to energy from the source after modification by the track.

    Abstract: There is described an apparatus for producing an electrical signal related to the varying concentration of a solution, for example a sugar solution. Light is inclinedly directed upon a surface of a prism which is in contact with the solution, so that light falling on one side of a boundary line, the position of which is a function of the concentration of the solution, is transmitted into the solution while light falling on the other side of this boundary line is totally reflected. The reflected light is directed towards an assembly including two photocells which are spaced apart in the direction of movement of the boundary as the solution concentration varies. The outputs of the two photocells are combined in a difference amplifier to yield a signal denoting that the solution concentration has reached a predetermined value dependent upon the position in said direction of movement to which the assembly is adjusted.
