Abstract

A position and movement meter is described, said meter having a carrying body (10) carrying a read pattern comprising at least two types of regions, and at least one read-out means (12) arranged to read the read pattern, the carrying body and the read-out means being movable relative to one another. The read pattern comprises a reflective surface, and the read-off means (12) comprises a source of light and a measurement means, which registers the manner in which light from the source of light is reflected by the various regions. The application also concerns a distance meter comprising such a meter.
