Title: Measuring optical interference
IPC: G01D5/353
Filed: 1979-08-02
Abstract: A method of measuring optical interference for use in incremental lengths and angular measurement, using an integrated optical arrangement, comprises the steps of coupling two modes 5, 6 (first and second laser beams) to a waveguide 2. The modes interfere within the waveguide 2, and the relative phase positions of both modes varied through a measuring operation is measured. An integrated optical arrangement for carrying out the method is characterised in that a multi-mode waveguide 2 is arranged between a carrier 1 and a cover layer 3. The effective refractive indices of the waveguide 2 differ with respect to two coupled modes comprising laser beams 5 and 6 such that an interference period results. The individual maxima of the modes are detected by a sequence of photodetectors 7 to 16 disposed upon the cover layer 3 and which are energetically connected to the waveguide 2 via coupling gratings (not shown). A first photodetector 7 of the sequence serves for measuring the resulting phase shift in  lambda /2 steps. A second photodetector (not shown), staggered relative to the first photodetector 7 at half an interference period, is provided to detect the direction of phase variation. The remaining photodetectors of the. sequence act as an optical vernier. The detectors detect the displacements in  lambda /2 diversion steps in dependence on the number of photodetectors. <IMAGE>
