Title:
METHOD AND INSTALLATION FOR THE MULTIDIMENSIONAL MEASUREMENT OF AN OBJECT
Document Type and Number:
WIPO Patent Application WO1985001793
Kind Code:
A3
Abstract:
The present invention relates particularly to an optical process with series detection of measurement. In such process and installations, an important disadvantage is mainly the fact that a very large number of receiver elements must be used, which exceeds by far the capacity as presently with electronic apparatus. For large tridimensional objects, another problem is to obtain a good resolution particularly for the third dimension, for example the height. The present invention provides a remedy to these problems by deflecting the lighting and representation light beam. Said deflection is effected so that, with respect to a defined reference object, it is possible to compensate for the displacement of the light beam in a direction corresponding usually to a co-ordinate axis. What is required is a receiver line or a unidimensional direction of receivers to obtain a high measurement dynamic, since all the receiver elements are at disposal to detect the differences of the object to be measured on one co-ordinate axis or in the direction of the axis of the lighting light beam.
