ABSTRACT:
The optical distance detecting or measuring device comprises a light source with an emitting optic for projecting a light beam according to the axis of the emitting optic onto a target to be measured and a first detector defining the receiving axis contained in the same reference plane as the emitting axis. The device comprises at least a second detector that is aligned with the first detector on an axis contained in a plane that is inclined at an angle α with respect to the reference plane, said angle being comprised between 10° and 170°. Alternatively, two emitters may be arranged in an inclined plane and one receiver in the reference plane. This arrangement allows a significant improvement of the performance of such a device.
