Abstract
The invention concerns a method for indirect and sequential measuring of the absolute position of an element ( ) comprising a binary coding produced by means of coding units ( ) of the same surface, relatively moving with respect to an element provided with a device for reading said coding ( ), said coding ( ) delimiting differentiated sectors each comprising an identical separating zone, called separator, and an zone identifying a single sector, called identifier, the list of the identifier codes being contained in a memory zone accessible via a device for processing binary data transmitted sequentially bit by bit by said reading device when the elements are relatively moving. The invention is characterised in that the separator coding comprises a binary sequence which is excluded from the identifier coding, thereby immediately identifying a separator, whose knowledge of the whole code indicates the identifier following it, then the position of its corresponding sector by scanning the memory zone containing the list of identifier codes.
