A rangefinder is a device that measures distance
from the observer to a target, for the purposes of surveying, determining focus
in photography, or
accurately aiming a weapon. Some devices use active
methods to measure (such as sonar, laser, or radar); others, available since
the nineteenth century, measure distance using trigonometry (stadiametric
rangefinders and parallax,
or coincidence rangefinders). They usually use a set of known
distances or target sizes to make the measurement.
