    摘要: An incident electromagnetic wave-field, preferably in the ultraviolet, visible or infrared spectral range, that is spatially varying in one dimension can be correlated with a fixed, one-dimensional test function, by means of a photo detector consisting of a multitude of rectangular photosensitive elements whose relative lateral widths vary in proportion to the local amplitude of the test function. Several such spatial correlation tracks for different test functions can be arranged in the direction perpendicular to the width modulation direction. Each correlation track provides the degree of correlation of the incident wave-field with a particular test function, by determining the correlation of these two signals in the optical domain, without the need for an additional analog or digital processor. This invention is particularly advantageous for application in optical encoders for the determination of lateral or rotational spatial displacement.

    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 solid-state charge sensor with high dynamic range and low readout noise comprises a semiconductor area (S) where charge is created and stored, an output gate (PG), a low-capacitance sense diffusion (sense), an overflow gate (OFG) and a high-capacitance overflow-charge-handling structure (OCH) that has either linear or non-linear charge-voltage response. The sense diffusion is employed for the high-sensitivity detection of low charge signals; the charge-handling structure (OCH) is used when larger charge signals are present, and the voltage on the overflow gate (OFG) defines the crossover point from small to large charge signals. A preferred application of the charge sensor is in photosensing of radiation. Photocharges can be generated and stored either in photodiodes or under photogates (PG), allowing the use of correlated double sampling techniques for the effective suppression of reset noise.

    摘要: The method serves for canceling errors caused by mismatch of different signal paths in a photodetector with a plurality (k) of storage elements for the photogenerated signals, as typically used in phase-measurement systems. The signal-capturing process is performed in at least two measurement cycles (j). A first cycle (j = 1) is executed with the conventional setup with no phase delay in the control signals. It is followed by further measurement cycles (j = 2, 3, 4) which use control signals shifted by a constant phase shift (90°). Corresponding signals are read out through different signal paths. At the end, the signals corresponding to a certain phase (Φ) are added, thus canceling possible offset values.
