A measuring device for optically measuring a distance to a target object including an emitter device for emitting an optical measuring beam to the target object, a capturing device comprising a detection surface for detecting an optical beam returned by the target object, and an evaluation device. The detection surface has a plurality of pixels, each pixel having at least one light-sensitive element and each of the plurality of pixels is connected to the evaluation device. The emitting device and the capturing device are configured in such a manner that the optical measurement beam returned by the target object simultaneously illuminates a plurality of pixels. The evaluation device is configured in such a manner that detection signals of a plurality of pixels are guided to at least one of the plurality of distance determining devices.

A sensor unit for detecting reference and measurement radiation for a distance measurement device has a sensor element and an optical shielding device. The sensor element has a first detection region for detecting measurement radiation and a second detection region for detecting reference radiation. The optical shielding device is positioned in relation to the sensor element and fastened, and the optical shielding device optically separates the first and second detection regions from each other. The optical shielding device further comprises a first recess and a second recess which are permeable to optical radiation of a first wavelength range.

A photon detector is disclosed that includes, in addition to an immobilizable photon-sensitive element, a photon transmission element. The photon detector is configured such that it can vary photon intensities impacting upon the photon-sensitive element and transmitted by the photon transmission element, for example, by modifying an absorption property or a defocusing property of the photon transmission element. Also, the immobile photon-sensitive element, which can be, for example a SPAD (Single Photon Avalanche Diode), always operates close to the optimal operating range and below an immobilization range. A distancing device that includes this type of photo detector is also disclosed.

A measuring device for optically measuring a distance to a target object includes an emitter device for emitting an optical measuring beam to the target object, a capturing device including a detection surface for detecting an optical beam returned by the target object, and an evaluation device. The detection surface has a plurality of pixels, each pixel having at least one SPAD (single photon avalanche diode) and each of the plurality of pixels is connected to the evaluation device. The emitting device and the capturing device are configured in such a manner that the optical measurement beam returned by the target object simultaneously illuminates a plurality of pixels. The evaluation device is configured in order to determine the distance between the measuring device and the target object based on the evaluation of detection signals of several pixels.

A measuring apparatus for optically measuring a distance to a target object is described. The measuring apparatus has a transmitting device for emitting periodically modulated optical measuring radiation towards the target object, a receiving device for detecting optical measuring radiation which returns from the target object, and an evaluation device for receiving and evaluating detection signals from the receiving device. The measuring apparatus also has a calibration device for calibrating the measuring apparatus, wherein the calibration device is designed to calibrate the measuring apparatus on the basis of detection of uncorrelated radiation which does not correlate with the modulated measuring radiation emitted by the transmitting device. In this case, the uncorrelated radiation may be in the form of background radiation. Alternatively, uncorrelated measuring radiation can be emitted by the transmitting device and can be detected by the receiving device.
