    • A measuring device for optically measuring a distance to a target object includes an emitter device for emitting an optical measuring beam to the target object, a capturing device including a detection surface for detecting an optical beam returned by the target object, and an evaluation device. The detection surface has a plurality of pixels, each pixel having at least one SPAD (single photon avalanche diode) and each of the plurality of pixels is connected to the evaluation device. The emitting device and the capturing device are configured in such a manner that the optical measurement beam returned by the target object simultaneously illuminates a plurality of pixels. The evaluation device is configured in order to determine the distance between the measuring device and the target object based on the evaluation of detection signals of several pixels.

    • An apparatus for detecting at least one substance present in a fluid flow includes at least one field effect transistor which acts as a measuring sensor, and at least one field effect transistor which acts as a reference element, the field effect transistors each having at least one source electrode, one drain electrode, and one gate electrode. The gate electrode of the field effect transistor which acts as the measuring sensor is sensitive to the at least one substance to be detected, and the gate electrode of the field effect transistor which acts as the reference element is essentially insensitive to the at least one substance to be detected. The source electrode of one of the field effect transistors and the drain electrode of the other of the field effect transistors are connected to one another and to a signal line. A method for detecting at least one substance present in a fluid flow by using the apparatus is also described, a potential of 0 volt being applied to the signal line and the current flowing on the signal line being measured.

    • An integrated circuit (IC) includes a photosensor array, some cells of which are reference cells that photosense throughout an application's energy range, while other cells of which are subrange cells that photosense within respective subranges. For example, the subrange cells can receive photons in their respective subranges from a transmission structure that has laterally varying properties, such as due to varying optical thickness. The reference cells may be uncoated or may also receive photons through a transmission structure such as a gray filter. Subrange cells and reference cells may be paired in adjacent lines across the array, such as rows. Where photon emanation can vary along a path, quantities of incident photons photosensed by subrange cells along the path can be adjusted based on quantities photosensed by their paired reference cells, such as with normalization.
    • 集成电路(IC)包括光电传感器阵列,其中一些单元是在整个应用的能量范围内照射的参考单元,而其他单元是在相应子范围内的光密度的子范围单元。 例如,子范围单元可以从具有横向变化的特性的传输结构接收其各自子范围内的光子,例如由于光学厚度的变化。 参考单元可以是未涂覆的,或者也可以通过诸如灰色滤波器的透射结构接收光子。 子范围单元格和参考单元可以在阵列中的相邻行中配对,例如行。 当光子发射可以沿着路径变化时,可以基于通过其配对参考细胞(例如通过归一化)照射的光量来调整沿着路径由子范围单元照射的入射光子的量。
