摘要： The present invention relates to a method for synchronizing the optical units of a photoelectric barrier and to such a photoelectric barrier. The synchronization method comprises the steps of transmitting radiation forming a synchronization signal from a first optical sender of the first optical unit; controlling a plurality of the optical receivers of the at least one second optical unit to monitor whether the synchronization signal has been received and performing a synchronization step if the synchronization signal has been received. The method further performs the step of defining at least one of said plurality of optoelectronic components to be used for the synchronization step.

摘要： A time-of-flight (TOF) sensor device is provided with features for correcting distance measurement offset errors caused by such factors as temperature, dynamic reflectivity ranges of objects in the viewing space, or other factors. In various embodiments, the TOF sensor device generates corrected distance values based on comparison of two different distance values measured for an object by two different measurement techniques, including but not limited to phase shift measurement, pulsed TOF measurement, distance measurement based on the focal length of the TOF sensor's lens, and comparison of distance variations with light intensity variations. In addition, some embodiments of the TOF sensor device perform self-calibration using internal waveguides or parasitic reflections as distance references.
