ABSTRACT:
A distance detecting arrangement employs at least two sensors having different ranges and resolutions of operation. Embodiments disclosed contemplate at least four modes of operation. In a first mode, only one sensor is employed. In a second mode, a longer range and lower resolution sensor is employed until a threshold value of distance is reached, at which point a shorter range and higher resolution sensor is employed. In a third mode, both the longer range and shorter range sensors are employed simultaneously. In a fourth mode, a low resolution profile is used to rescan the object with the high resolution sensor to provide a high resolution profile measurement. Embodiments facilitate the method disclosed by including a beam redirecting apparatus and preferably include a servo position system that can move the sensors and the object relative to each other.
