  • TOf distance sensor and method for operation thereof
    Patent number: 9377532
    Abstract: A TOF distance sensor is proposed, for measuring a distance from an object, comprising an electronics apparatus for generating a modulation signal and for generating four correlation signals, which are phase shifted with respect to one another and which have the same period as the modulation signal; a radiation source for emitting radiation, which is modulated by the modulation signal; a reception apparatus, which has a predetermined spatial relationship with respect to the radiation source, for receiving radiation reflected by the object; a correlation apparatus for correlating the received radiation or a corresponding variable with respectively one of the four correlation signals in order to form four corresponding correlation values; a difference-forming apparatus for forming two difference correlation values from the difference between respectively two of the correlation values; a calculation apparatus embodied to calculate the distance with a predetermined linear dependence on the two difference correlat
    Type: Grant
