This paper discusses some areas of industrial applications of high accuracy laser rangefinders and laser rangefinding techniques that require noncontact survey and profile measurements to be made to points of diffusely reflecting objects that are difficult to reach. Structural layouts and characteristics are given for phase and pulsed laser rangefinders.
