Abstract
A system and method are provided for determining a distance to a target. The method includes sending light, at a first time, to a light reflector mounted in a reflector device, receiving light reflected from the light reflector at a second time, and determining the distance to the reflector device using the difference between the first time and the second time. The reflector device has a first lateral surface, a second lateral surface parallel to the first lateral surface, and a rod surface extending from the first lateral surface to the second lateral surface. The reflector device includes sockets arranged in the rod surface with a light reflector mounted in each socket. The sockets may be arranged in a plurality of rows with possibly a plurality of sockets in each row. The reflector device may be mounted as an insert to or at the top of a target to determine the distance to the target.
