Abstract: An optoelectronic sensor for detecting three-dimensional image data from a monitored zone is provided that has an illumination unit for illuminating the monitored zone with modulated transmitted light, a light receiver for a simultaneous light reception of the transmitted light remitted by objects in the monitored zone at at least two locations at a mutual distance corresponding to a first resolution pattern, and a control and illumination unit that is configured to determine times of flight from properties of the modulated and remitted transmitted light and to detect three-dimensional data in a second resolution pattern finer than the first resolution pattern by at least one measurement repetition with a light reception from at least two other locations shifted with respect to the first resolution pattern.

Abstract: A transmission/reception module for an optoelectronic sensor is provided that has a light transmitter having a transmission optics and that has a light receiver having a reception optics, wherein an irradiation angle of transmitted light of the light transmitter is smaller than a reception angle of received light incident on the light receiver; the light transmitter and the light receiver are arranged coaxially; and the transmission optics and the reception optics are formed as a common optics. The light transmitter and the light receiver are here indirectly micromechanically connected to one another.
