摘要： For acquiring a 3-D image of a scene, the scene is illuminated with modulated light emitted by an illumination unit and imaged onto an array of lock-in pixel sensor cells, which detect the previously emitted light after it has been scattered or reflected by an object or a living being in the scene. One determines the modulation phase of the light detected at the lock-in pixel sensor cells and provides a reference modulation phase that stands in a known relationship with the modulation phase of the light at the time of the emission. Based upon the reference modulation phase and the modulation phase of the light detected at the lock-in pixel sensor cells one then calculates depth information on the scene. The modulated light is emitted by a plurality of individual light emitting devices of the illumination unit, each of the light emitting devices emitting a part of the modulated light, and the reference modulation phase is provided as an average of the modulation phases of the parts of modulated light emitted by the light emitting devices.

The capacitive detector is configured for driving an alternating current into the heating element and for producing an output indicative of capacitance based upon the alternating current. The choke has a first (30) and a second (32) winding for connecting the heating element with the heating current supply. The choke comprises a third winding (34) connected in parallel of the first and/or second winding. The capacitive detector is configured for measuring a portion of the alternating current flowing across the third winding and for taking into account the measured portion of alternating current when producing the output.

摘要： A capacitive sensing system (24) for being connected to a heating element (12) producing heat upon electrical current being caused to flow there across comprises a capacitive detector connectable to the heating element and a common mode choke (28) for connecting the heating element with a heating current supply (22). The capacitive detector is configured for driving an alternating current into the heating element and for producing an output depending on the capacitive load, which the alternating current is subject to. Depending on the object to be sensed, the capacitive load is variable in a range between a minimum value and a maximum value. The common mode choke represents an inductive load in parallel of the capacitive load. The capacitive load and the inductive load contribute together to a complex impedance. The inductive load dominates the capacitive load. A compensation capacitor is arranged in parallel of the choke. The compensation capacitor represents an additional capacitive load also contributing to the complex impedance. The compensation capacitor is dimensioned such that the sum of the additional capacitive load and the maximum value amounts to at least 50 % of the inductive load.

摘要： A method for 3D imaging of an actively illuminated target region comprises emitting intensity-modulated light at a variable modulation frequency into the target region. The emitted light is scattered/reflected in the target region depending on the optical properties of the objects or beings present therein. A scattered and/or reflected fraction of the light is detected during an integration time interval by phase-sensitive integration in each pixel of an imaging sensor. The modulation phase between the emitted and the detected light is determined and spatially resolved. Distance information is calculated based on the spatially resolved modulation phase and an average frequency of the modulation frequency.
