A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
A height finder radar is a type of 2-dimensional radar that measures altitude of a target. The operator slews the antenna toward a desired bearing , identifies a target echo at a desired range on the range height indicator display, then bisects the target with a cursor that is scaled to indicate the approximate altitude of the target.
