Abstract: The invention relates to a method for light detecting and ranging (LIDAR) measurement of speeds, in which a laser beam is directed at the medium to be measured, and radiation which is subsequently emitted from the medium (16) is measured by a detector. In order to optimize the measurement, a spatial measurement range can be selected by activation and/or deactivation of the detector for at least one predetermined or regulated time duration of less than about 500 ?s after emission of a laser pulse to the medium to be measured. Furthermore, a direct reception Doppler LIDAR apparatus can be used to perform the method.

Abstract: The invention relates to a method for Doppler light detection and ranging (LIDAR) measurement of speeds. A laser beam is directed at the medium to be measured, and radiation which is then emitted by the medium is measured by a detector. In order to allow better control of the dynamic range of a direct reception Doppler LIDAR apparatus, a multiplicity of laser pulses can be transmitted per measurement, and a multiplicity of laser pulses can be received by the detector per measurement. A direct reception Doppler LIDAR apparatus can be suitable for carrying out the method.

Abstract: There is provided a hybrid cable that comprises a coaxial cable with an outer conductor and a hollow inner conductor that encloses an inner space. The hybrid cable according to an exemplary embodiment of the present invention may comprise a data line that is arranged in the inner space of the inner conductor.
