Patent GB-2255187-A (GB)
Title: Method and apparatus for measuring and determining a rotation angle of a rotating object
Inventor: TANK VOLKER
IPC: G01D5/249
Filed: 1992-04-24
Abstract: In a method of measuring and determining a rotation angle of a rotating object, a clock track corresponding to a desired angular resolution is applied on a magnetic, optical or optomagnetic storage medium. The storage medium is then rotated synchronously with the rotating object, and during the operation a pulse sequence corresponding to the clock track is read from said storage medium. The read pulse sequence is supplied for further processing to following electronics in which the actual rotation angle is firstly stored in a FIFO memory and secondly directly available for further uses. Apparatus for measuring and determining a path difference in Michelson interferometers in which path differences are generated via a rotary movement, e.g. of a rotating retroreflector, is described. During operation the pulse sequence is read and supplied to following signal electronics in which from the pulse sequence the desired clock pulse and thus the path information is obtained. Consequently, with the invention a laser is necessary only for generating the clock pulse once and thereafter is no longer required. As storage medium, magnetic, optical or optomagnetic carriers are used, for example in the form of floppy discs, compact discs, WORM memories, and the like.
