Abstract

1301105 Selective signalling KOMBINAT MEDIZIN-UND LABORTECHNIK LEIPZIG VEB 16 Oct 1969 50910/69 Heading G4H The refractive index of gas or liquid is measured photoelectrically by using a plurality of different pairs of interfering light beams so arranged that when sensed binary coded signals representing the refractive index are produced.
