Abstract:
A TOF camera for determining a distance to an object comprising: a radiation source configured to emit electromagnetic radiation toward the object, radiation-sensitive sensor elements configured and arranged to detect the electromagnetic radiation reflected/scattered by the object, an optical element arranged to influence the emitted electromagnetic radiation in the radiation path of the reflected/scattered electromagnetic radiation between the object and the sensor elements, a computing unit electrically connected to the radiation source and sensor elements configured to determine a time duration required by the electromagnetic radiation from the radiation source to the object; from the object to the sensor elements; and to determine the distance between the TOF camera and the object depending on the time duration determined. The sensor elements and/or the optical element are configured such that different sensor elements detect the reflected/scattered electromagnetic radiation from different solid angles on the far side of the optical element.
