A method and apparatus for precision distance measurement are provided to perform accurate measurement of distance to an object according to light spots formed on the light-receiving surface of a detector even when multiple reflections are involved. A beam of light emitted from a light source and reflected from the object is focused on the viewing surface as light spots through an optical member. The focal position of a reflected beam of light is determined according to a focal position detection process. When there are peaks in a luminosity curve generated on the detector, prior to performing the focal position detection process, the peaks are separated into individual light spots and a correct light spot for deriving the precise distance is selected by a selection process. The invention also provides methods for each of spot separation, spot selection, luminosity distribution restoration, and focal position detection.
