Abstract

An electronic distance meter includes an optical unit which emits light to a target object and receives the light reflected by the target object with a light receiving element, a measuring unit which calculates a length of round-trip time taken for the light to reciprocatively travel to the target object and measures a distance to the target object according to the round-trip time of the received light, a light receiving system which receives and condenses the light reflected by the target object, and an optical guide which guides the light condensed by the light receiving element to the light receiving system, including a multi-mode graded index fiber and a multi-mode step index fiber coupled with each other.
