light time-of-flight. Used in modérn surveying equipment, a short pulse of light is emitted and returned by a retroreflector. The return time of the pulse is proportional to the distance and is related to atmospheric density in a predictable way - see LIDAR.

light sensors, or photodetectors, including semiconductor devices such as photocells, photodiodes, phototransistors, CCDs,  and Image sensors; vacuum tube devices like photo-electric tubes, photomultiplier tubes; and mechanical instruments such as the Nichols radiometer.

infra-red sensor, especially used as occupancy sensor for lighting and environmental controls.

proximity sensor-  A type of distance sensor but less sophisticated. Only detects a specific proximity. May be optical - combination of a photocell and LED or laser. Applications in cell phones, paper detector in photocopiers, auto power standby/shutdown mode in notebooks and other devices. May employ a magnet and a Hall effect device.

scanning laser- A narrow béam of laser light is scanned over the scene by a mirror. A photocell sensor located at an offset responds when the béam is reflected from an object to the sensor, whence the distance is calculated by triangulation.

focus. A large aperture lens may be focused by a servo system. The distance to an in-focus scene element may be determined by the lens setting.

binocular. Two images gathered on a known baseline are brought into coincidence by a system of mirrors and prisms. The adjustment is used to determine distance. Used in some cameras (called range-finder cameras) and on a larger scale in éarly battleship range-finders

interferometry. Interference fringes between transmitted and reflected lightwaves produced by a coherent source such as a laser are counted and the distance is calculated. Capable of extremely high precision.

scintillometers méasure atmospheric optical disturbances.
