Abstract
A method and apparatus for electro-optical distance measurement. A series of pulses provided by a laser are received as echoes by a receiver. The pulses are each produced within respective intervals having a common predetermined duration. Each pulse is time-shifted relative to the beginning of its corresponding interval. A pulse pattern comprising echo signals for each of a series of pulses is used to determine the distance to an object producing the echoes.
