摘要： The present disclosure relates to an optoelectronic device comprising: a light source configured to emit light pulses periodically; an array of pixels each configured to detect an amount of return light falling in each of a subset of two or more time intervals forming a detection time window of the pixel; and a time window position code generator (575) configured to generate a sequence of time window position codes; each pixel comprising: a memory (601) configured to store a first reference time window position; a time window code comparator (580A) configured to compare a first time window position code of said sequence with the first reference time window position; and a timing sequence generator (580B, 580C) configured to generate, when the comparison indicates a match, at least one time window control signal (g0, g1, g2, g3).

摘要： An MTA scanner for providing a point cloud comprising 1.) a light pulse source for generating a first pulse train with a first repetition rate, such that first ambiguity distance is less than an envisaged measurement range, and a second pulse train with a second repetition rate, such that second repetition rate is a proper fraction of the first repetition rate, 2.) a transmission unit to transmit the first scanning pulses and the second scanning pulses to respective transmission directions, 3.) an acquisition unit to acquire first and second scanning pulses reflected from object points in the environment, and 4.) an evaluation unit to assign the acquisition events to the respective first and second transmission events, using an MTA disambiguation based on the first and second repetition rates.

摘要： A plurality of pixels (100) in a solid-state imaging device (10) each include: a light receiving circuit (101) that includes a light receiving element (105) performing photoelectric conversion, sets, by an exposure signal, a photoelectric time for performing the photoelectric conversion in the light receiving element (105), and outputs a light reception signal depending on whether or not incident light has reached the pixel (100) within the photoelectric time; a counter circuit (102) that counts, as a count value, the number of times the incident light has reached the pixel, based on the light reception signal received from the light receiving circuit (101); a comparison circuit (103) that sets a value corresponding to the count value as a threshold, and sets a comparison signal to an on state in the case where the count value is greater than the threshold; and a storage circuit (104) that receives the comparison signal and a time signal, and stores, as a distance signal, the time signal when the comparison signal is in the on state.

摘要： Die Erfindung betrifft ein Verfahren zur Detektion eines Objekts, bei welchem in einen Sendebereich mittels einer Lichtquelle wiederholt Pulse von Sendelicht ausgesandt werden, aus dem Detektionsbereich empfangenes Empfangslicht mittels einer Detektionsvorrichtung, die mehrere Detektoren aufweist, erfasst wird, und ein mehrere Detektoren umfassender Auswertebereich definiert wird, innerhalb dessen Empfangslicht auf die Detektoren trifft. Das Verfahren zeichnet sich dadurch aus, dass innerhalb des Auswertebereichs mehrere Teilregionen festgelegt werden, unter Verwendung mehrerer aufeinanderfolgender Pulse von Sendelicht die Teilregionen zumindest teilweise nacheinander ausgewertet werden und die Auswertungen der Teilregionen kombiniert werden, um die Anwesenheit eines Objekts in dem Detektionsbereich festzustellen.
