Abstract : The use of lasers in Soviet geodetic instruments has been confirmed by a photograph and brief description of a device called the GD-314 phased-light radio rangefinder. The equipment is designed to measure distances up to 2000 m with an accuracy of 2 cm. The light source is a gallium-arsenide, semiconductor diode laser. The continuous radiation wavelength is 860 nm, and the output is 0.5 mW. Distance measurements are made at radiation frequencies of 100 kc and 10 Mc. There are three component parts of the device: a transmitting and receiving unit weighing 6 kg, a measuring unit weighing 5 kg, and a power supply weighing 15 kg (dry-cell batteries which operate continuously for 50 hours).
