Abstract
A laser ranger has a rotational light source and a receiver. The rotational light source is used to provide a light beam with a pre-determined rotation speed. The receiver detects the time period for the light beam to travel from a first position to a second position of the receiver, such that the distance between the rotational light source and the receiver is calculated based on the detected time period and the spacing between the first and second positions of the receiver.
