Abstract: A light scanning system includes a transmitter configured to transmit a transmit light beam along a transmission path; a microelectromechanical system (MEMS) mirror arranged on the transmission path and configured to oscillate about a first scanning axis to steer the transmit light beam in a first dimension; a macro scanner arranged on the transmission path and on a receiver path, the macro scanner configured to rotate about a second scanning axis to steer the transmit light beam in a second dimension, where the macro scanner is further configured to receive a receive light beam that is produced from the transmit light beam via backscattering, and where the macro scanner is configured to direct the receive light beam further along the receiver path; and a photodetector configured to receive the receive light beam from the macro scanner and generate a measurement signal representative of the receive light beam.

Abstract: An optical device for detecting a light beam reflected by a remote target comprises a light source, which is designed to emit the light beam in a predetermined direction at the remote target, and a primary lens, which is designed to focus the light beam reflected by the remote target into a first focal point. The optical device further comprises a relay lens system, which is arranged in such a way that the first focal point is located between the primary lens and the relay lens system and which is designed to focus the light beam reflected by the remote target and diverging starting from the first onto a second focal point. A detector unit is essentially arranged in the second focal point. A diaphragm is arranged within a cross-section, which is normal to the optical axis, of the light beam reflected by the remote target between the first focal point and the relay lens system.

Abstract: Apparatus for measurement of the reception time of a pulse in a receiving system, which contains at least one receiving channel with a non-linear transmission response, which receiving channel produces at its output a received signal, having a memory, in which the received signals of reference pulses with a predetermined different amplitude are available as reference signals with respect to a time scale, and having an evaluation device, which is connected to the receiving system and to the memory and compares a received signal with each reference signal with a variant time offset in order to determine that reference signal and that time offset for which the comparison discrepancy is a minimum, and outputs this time offset as the reception time with respect to the time scale.
