Abstract

In a triangulation distance measuring system several position sensing means are provided in order to sense a certain predetermined part of the total measuring range each. Hereby the resolution can be increased without increasing the cost due to more expensive detector elements in the form of for example PSD-elements or CCD-arrays and more expensive lens arrangements having high requirements on accuracy. Further more an almost arbitrary resolution can be obtained by means of providing more detector elements for a given measured range.
