ABSTRACT:
A proximity device for use in determining a distance and an angular displacement between the proximity device and an object or nearest surface of an object whereby alignment can be implemented. The proximity device contains a transmitter section for transmitting signal energy, an energy source for outputting the signal energy, a dual-channel receiver section, a plurality of energy sensors for receiving signal energy reflected from an object or nearest surface of an object and a channel-control section. Within the dual-channel receiver section there are means for determining the relative distance and an angular displacement to the object or surface of the object from the reflected signal energy.
