摘要： The central idea of the present invention is that a readout result of an optical detection unit which is based on accumulating photocharges can be improved when the charge carriers accumulated on a photodiode capacitance can be transferred to a readout capacitance before being read out by a readout unit, and when the state of the readout capacitance can be read out in a non-destructive manner by the readout unit, so that a noise portion in the readout signal can be corrected by reading out the readout capacitance during charge accumulation and again reading out the readout capacitance after the end of charge accumulation. Additionally, it becomes possible by the transfer to the readout capacitance to vary the sensitivity of the optical detection device within broad limits and to record a sequence of successive light pulses, without having to reset a photodiode before recording every single light pulse.

摘要： A device for reading out image data of a sub-range of an image captured by an image sensor is described, the image sensor including a plurality of image sensor elements which can be read out by an activation signal sequentially appliable to same according to a predetermined clock signal, wherein the image sensor elements outputting the image data for the sub-range can be determined by means of an activation pattern. The device comprises a plurality of branch blocks connected in series storing the activation pattern, wherein each of the branch blocks, depending on the activation pattern, applies the activation signal received to one or several image sensor elements associated with a branch block or passes same on to a subsequent branch block or a terminating element. The activation pattern is stored in the branch blocks substantially simultaneously to the activation signal. No delay or latency times, respectively, occur in the sensor readout.

摘要： The central idea of the present invention is that the resetting of the energy store associated with the receiver prior to every detection interval and/or prior to every exposure period, during which the energy stored in the energy store is to be changed in accordance with the output signal of the receiver so as to use the state of the energy store following the reception interval as information about the object may be avoided by setting the sensitivity of the receiver, which determines the level of the output signal at a specified electromagnetic radiation, higher in at least one instance, and lower in at least one instance between two resetting events, or by varying the sensitivity. The noise contribution provided by the resetting operations is hereby avoided, which is why the benefit of the accumulation and/or integration may be exploited across several reception intervals without this noise contribution.
摘要翻译：本发明的中心思想是在每个检测间隔之前和/或在每个曝光期之前与接收器相关联的能量存储器的复位，在此期间存储在能量存储器中的能量将根据接收器的输出信号，以便使用接收间隔之后的能量存储器的状态，作为关于对象的信息可以通过设置确定在指定的电磁辐射下的输出信号的电平更高的接收机的灵敏度来避免在至少一个实例中，并且在两个重置事件之间的至少一个实例中较低，或通过改变灵敏度。因此避免了由复位操作提供的噪声贡献，这就是为什么可以在几个接收间隔内利用积累和/或积分的优点而没有这种噪声贡献的原因。

摘要： A sensor element has a field effect transistor sensitive to a physical quity to be detected. The gate electrode of the transistor is implemented as a floating gate. The sensor element has therefore integrated therein a sensor cell and a non-volatile memory. The operating point of the transistor can be adjusted permanently by means of the floating gate on which charges can be stored in a non-volatile manner. In addition, charges corresponding to a detected physical quantity can be stored on the floating gate via a simple circuit in a non-volatile manner.

摘要： The present invention relates to a concept for optical distance measurement, wherein a radiation pulse is emitted in the direction of an object of measurement. At least two different transfer gates which couple a photoactive region to at least two different evaluating capacities are driven during different drive intervals so that charge carriers generated during the drive intervals by a radiation pulse reflected from the object of measurement and/or by ambient radiation can be transported from the photoactive region to the evaluating capacities each coupled to the at least two transfer gates. Another transfer gate is driven during a time outside the drive intervals of the at least two transfer gates to connect the photoactive region to a reference potential terminal acting as a charge carrier sink during the time outside the drive intervals of the at least two transfer gates.

摘要： An electromagnetic radiation detector includes a semiconductor substrate of a first doping type, a well in the semiconductor substrate of a second doping type, two or more detector terminal doping regions, two or more transfer gates, and a collection gate. The first and second doping type are different and the well includes a rising dopant concentration in a direction parallel to a surface of the semiconductor substrate. The two detector terminal doping regions are arranged at least partly in a terminal region of the well. The detection of the electromagnetic radiation is based on a generation of free charge carriers by the electromagnetic radiation in a detection region of the well. The transfer gates control a transfer of free charge carriers to be or not to be evaluated in a region of the well. The collection gate collects free charge carriers in the stated region of the well.

摘要： The present invention describes an optical distance measuring device having a pulsed radiation source that is implemented to transmit, in a temporally contiguous radiation pulse period, a radiation pulse having a pulse duration tp that is shorter than the radiation pulse period, and to transmit no radiation pulse in a temporally contiguous dark period. Further, the optical distance measuring device includes a detector for detecting different amounts of radiation in two overlapping detection periods during the radiation pulse period to capture reflections of the radiation pulse at an object surface and a background radiation and/or in two overlapping detection periods during the dark period to capture background radiation. The optical distance measuring device further includes an evaluator determining a signal depending on a distance of the optical distance measuring device to an object based on the detected amount of radiation. Further, the present invention provides a method for optical distance measurement and for multiple sampling.

摘要： An indirect detection of the reflected radiation pulses, when measuring a distance by means of the photoeffect, allows considerably expanding the usability of the distance sensor and the distance measuring method, wherein the adaption to a new field of application only requires little design changes. Since in the external photoeffect the photoelectrons are ejected from the material irradiated photon by photon or quantum by quantum and the photons, when being ejected, only require a certain minimum energy and correspondingly the radiation used for irradiation only requires a sufficiently small wavelength, the external photoeffect allows detecting radiation over a large spectral range. When interferences occur in a certain wavelength range in a certain field of application, the operating wavelength range of the distance sensor technology may at first simply be set to another spectral range by using such an irradiation source having a spectrum outside the spectral range containing the interferences.
摘要翻译：当通过光效测量距离时，反射辐射脉冲的间接检测允许显着扩展距离传感器的可用性和距离测量方法，其中适应于新的应用领域仅需要很少的设计变化。由于在外部光电效应中，光电子通过光子或量子的量子从材料照射的光子中喷出，并且当被喷射时，光子仅需要一定的最小能量，相应地，用于照射的辐射仅需要足够小的波长，外部光电效应允许在大的光谱范围内检测辐射。当在某一应用领域中发生特定波长范围内的干扰时，距离传感器技术的工作波长范围可以首先通过使用具有包含干扰的光谱范围之外的光谱的照射源简单地设置到另一个光谱范围。
