Abstract
Provided is a range finder. The range finder comprises a light-emitting unit, a light-receiving unit, a reflection mirror, an actuator, and a controller. The light-emitting unit emits a light pulse, and a light-receiving unit detects reflected light incident thereto. The reflection minor reflects the light pulse emitted from the light-emitting unit to a measurement space, and reflecting the reflected light reflected by an object in the measurement space so that the reflected light is incident to the light-receiving unit. The actuator allows the reflection minor to move. The controller obtains distance information from a signal detected by the light-receiving unit, and obtains location information from the actuator.
