Abstract
The invention relates to a distance measurement apparatus for measuring the time of flight of electromagnetic signals, having at least: a transmitter for transmitting coded transmission signals according to a pattern specified by a coder, a receiver for detecting the signals reflected by at least one object as receive signals, a counter unit having a time counter for writing time counter values, which are generated in each case with the transmission of the transmission signals and the receipt of the receive signals, into at least one register, and a control and evaluation unit for calculating the time of flight on the basis of decoding the receive signals and reading the register of the counter unit.
