ABSTRACT OF THE DISCLOSURE An apparatus for detecting distance to an object is disclosed, which includes a taking lens for collecting a light from an object, a first lens device for forming the light from the object and through the taking lens to a parallel light bundle when the object is positioned at the focal point of the taking lens, a second lens device for focussing the light through the first lens device, a light sensing device for receiving the light through the second lens device, a separating device for separating the light from the first lens device to to least two bundles of light which are shifted perpendicularly to the optical axis of the second lens device with each other, and a detecting device for detecting the displacement of the multiple images on the light sensing device caused by the separated bundles of light by the separating device when the object is not at the focal point of the taking lens and for generating the output varying with the distance to the object.
