Mobile telephone with distance, angle or speed measuring functions has evaluation unit for measuring propagation time of received laser beam and calculates associated distance

摘要

In addition to the modules required for telecommunication, the mobile telephone includes a laser transmitter-receiver with a laser source, and a lens for focussing the emitted radiation. Measurement data from an evaluation unit are supplied to a unit for transmitting the data via a mobile radio network (12) to a remote station, e.g. a personal computer (10). The evaluation unit measures the propagation time of a received laser beam (7), and calculates the associated distance.
