Abstract
A system for locating an object in latitude and longitude is disclosed. A rotating and oscillating mirror makes a laser beam deflect. A sensor fixed to the object indicates the locating instant. A screen that scatters and/or reflects towards a second sensor, on which are stretched reflecting and/or scattering cords, provides latitudinal and longitudinal position-identification of the deflection of the beam. The invention can be applied to robotics.
