Abstract
The present invention relates to an apparatus for measuring a distance, the apparatus including a light transmitter including a light source configured to emit a light, and a collimator lens configured to emit a light by converting the light emitted from the light source to a collimation light, and a light receiver including a first mirror configured to reflect the collimation light emitted from the collimator lens to an object, a lens configured to concentrate a light reflected or dispersed from the object to a spot, and a photo-detector configured to form a spot concentrated with light on the lens, wherein an optical axis of the light source matches a rotation shaft of the photo-detector, the light transmitter is fixed and the light receiver rotates about the optical axis of the light source.
