摘要： A method for determining a distance between a distance measuring device and an object includes the steps of illuminating the object with a short light pulse and long light pulses, outputting a signal value Uref at the end of an integration gate with an invariable delay between the emission start point in time of the short light pulse and integration start point in time Δs, forming a convolution function fc:=U(τ) from the intensity of the light arriving on the photo element and Δs with a respective variable delay τ for each long light pulse between the emission start point in time of the long light pulses and the integration gate, the variable delays being different from each other to form the convolution function, identifying the delay τc in the convolution function which corresponds to Uref, and calculating the distance by using the delay τc in the convolution function.

摘要： A method is provided for illuminating an object and for determining a distance value R. The object is illuminated with a light source and the light intensity of the light source is switched at a time T0 from an intensity Iout,h to an intensity Iout,l being lower than Iout,h and switched back to Iout,h at a time T0+Tn. A signal value U is outputted at the end of an integration window time period which has such a predetermined delay relative to T0 that either Ttof or Ttof+Tn is between an integration start point in time Tsd of the integration window time period and an integration end point in time Tsd+Ts, with Ttof being a point in time when light with the intensity Iin,l arrives first at the photo element, and Ts is longer than Tn.

摘要： A distance camera includes at least one photo element, a trigger generator activating the photo element during a temporal integration gate, a light source illuminating an object with light pulses having a predetermined temporal intensity profile with a duration Tp, and an intensity sensor determining the intensity Ip of the light pulses arriving on the photo element. The integration gate has a predetermined delay to the light pulse emission start point in order to capture the light pulses back reflected from the object. The photo element outputs a signal value U at an integration end point in time T1e and in accordance with an intensity Ip and a duration of the light pulse arriving on the photo element during its activation.

摘要： Imaging system includes pixel groups and a trigger generator to generate reset signals and a transfer signal. Each pixel group includes pixels and a programmable memory element to store a first or a second value. Each pixel includes a pixel circuit with a photodiode and a storage capacitance. The pixel circuit, the trigger generator, and the memory element are interconnected to permit the photodiode to be held at a constant voltage when the trigger generator sends the reset signal to the pixel circuit. When the reset signal is switched off, the photodiode accumulates a charge while being irradiated. When the transfer signal is received, the charge is transferred to the storage capacitance. The memory element blocks the transfer signal from arriving on all the pixel circuits when it has stored the first value and passes the transfer signal to all the pixel circuits when it has stored the second value.
