摘要： The aim of the invention is to eliminate the resetting of the energy accumulator, assigned to the receiver, prior to each detection interval or to each illumination period, during which the energy stored in the energy accumulator is modified according to the output signal of the receiver in order to use the state of the energy accumulator after the receiving interval to gain information about the object. To achieve this, the sensitivity of the receiver (50), which determines the intensity of the output signal for a fixed electromagnetic radiation is adjusted upwards and downwards at least once, or is varied between two reset events (68, 70). The noise contribution produced by the reset operations (68, 70) is thus eliminated, permitting the use of the accumulated or integrated charge over several receiving intervals without a noise contribution.

摘要： The indirect detection of reflected radiation pulses (28) during distance measurement by means of photoelectric effect enables the applicability of the distance sensor or the distance measuring method to be significantly broadened, the adaptation to a novel area of use only requiring minor design modifications. With the external photoelectric effect, the photoelectrons (68) are emitted photon by photon or quantum by quantum from the irradiated material (54), the emitted photons only requiring a minimum amount of energy and the radiation used for the irradiation thus only requiring a sufficiently small wavelength. As a result, the external photoelectric effect enables radiation over a large spectral area to be detected. If faults occur in a defined area of application, in a certain wavelength range, the working wavelength range of the distance sensor system can be first easily adjusted to another spectral range, using a radiation source (12) comprising a spectrum outside of the spectral range containing faults.

摘要： A new pixel in semiconductor technology comprises a photosensitive detection region (1) for converting an electromagnetic wave field into an electric signal of flowing charges, a separated demodulation region (2) with at least two output nodes (D10, D20) and means (IG10, DG10, IG20, DG20) for sampling the charge-current signal at at least two different time intervals within a modulation period. A contact node (K2) links the detection region (1) to the demodulation region (2). A drift field accomplishes the transfer of the electric signal of flowing charges from the detection region to the contact node. The electric signal of flowing charges is then transferred from the contact node (K2) during each of the two time intervals to the two output nodes allocated to the respective time interval. The separation of the demodulation and the detection regions provides a pixel capable of demodulating electromagnetic wave field at high speed and with high sensitivity..

摘要： A time-of-flight imager pixel has a light-sensitive region, a first and a second integration gate associated with the light-sensitive region, a first and a second sense node, a first output gate arranged between the first integration gate and the first sense node and a second output gate arranged between the second integration gate and the second sense node. The method for operating such a pixel comprises the steps of:
a) exposing the light-sensitive region to light so as to optically generate charge carriers;
b) collecting the charge carriers alternatively under the first and second integration gates;
c) adjusting voltages of the first and second output gates and the first and second integration gates, thereby transferring a first portion of the charge carriers from the first integration gate into the first sense node and a second portion from the second integration gate into the second sense node;
d) calculating time-of-flight information based on the first and second portions of charge carriers.
e) adjusting at least one voltage so as to transfer, if respectively the first and/or second integration gate is close to or in saturation, an amount of charge carriers form the first and/or second integration gate into the first and/or second sense node; and
f) testing whether a voltage change exceeding a given threshold was thereby provoked in the first and/or second sense node.

摘要： Light projected by a light projecting portion and reflected by an object is received by two sensor arrays (105, 106). Difference signals between signals respectively added by ring CCDs (113b, 114b) in correspondence with the ON and OFF states of the light projecting portion are calculated, and the distance to the object to be measured is calculated on the basis of the relative values of the positions of the difference signals on the sensor arrays (105, 106). The two sensor arrays (105, 106) form the base length, and the light projecting portion (104) is disposed at a position offset from the base length.
