  • Patent number: 9794490
    Abstract: A light speed camera system, with a camera module, which has a light speed photo sensor, preferably based on mixed photo detection, having at least one reception pixel, and with an illumination module which has an illumination light source, wherein the illumination module and the camera module each have a transmission circuit which is formed in such a way that a first signal as a differential signal and a second signal as a modulated basic voltage can be transmitted between the camera module and illumination module via a differential signal line is provided.
    Type: Grant

  • Patent number: 9465111
    Abstract: A time-of-flight camera, having a time-of-flight sensor, which has at least one receiving pixel and is configured as a photomixing detector, having an illumination means, and having a modulator, which is connected to the time-of-flight sensor and to the illumination means, wherein a control sensor is arranged in the region of the illumination means such that at least some of the radiation emitted by the illumination means can be received by the control sensor is provided.

  • Patent number: 9462168
    Abstract: A time-of-flight camera system includes a photosensor having at least one receiving pixel and a source of illumination. A modulator is configured to provide a modulation signal to the photosensor and to the source of illumination. A control sensor is connected to at least one reference light source or an electric mixer. The control sensor is disposed in a vicinity of the source of illumination such that the control sensor receives at least a portion of the radiation emitted by the source of illumination. The control sensor is configured to provide an electric output signal that substantially matches an intensity-over-time curve of the received radiation.
