Patent number: 11762070Abstract: A distance measuring device includes a light emission portion for emitting light; a light receiving portion for receiving measurement light that is emitted by the light emission portion and reflected by a measurement object, the light receiving portion comprising a plurality of pixels, each pixel having at least one light receiving portion and outputting a light reception signal that depends on the measurement light incident on the pixel; a discrimination portion for discriminating whether the pixel receives measurement light; a pixel output control portion for selectively outputting the light reception signal of each pixel individually, depending on the determination result of the discrimination portion; and an evaluation portion for receiving the light reception signals output by the pixel output control portion and outputting a distance signal that is indicative of a distance between the measuring device and the measurement object based on these light reception signals.Type: GrantFiled: August 19, 2019Date of Patent: September 19, 2023Assignees: OMRON Corporation, Politecnico di MilanoInventors: Yuki Matsui, Ken Nakamuro, Franco Zappa, Federica Villa, Rudi Lussana

Patent number: 11520047Abstract: A distance measuring device includes a light emission portion configured to emit light; a light receiving portion configured to receive measurement light that is emitted by the light emission portion and reflected by the measurement object, the light receiving portion comprising a plurality of pixels configured to output light reception signals that depend on the received measurement light; a plurality of determination portions configured to receive the light reception signals and to determine characteristic values from the received light reception signals, and an evaluation portion that is connected to the plurality of determination portions, the evaluation portion being configured to calculate a distance from the characteristic values determined by the determination portions. Each of the plurality of determination portions is configured to receive the light reception signals only from a plurality of non-adjacent pixels.Type: GrantFiled: August 8, 2019Date of Patent: December 6, 2022Assignees: OMRON Corporation, Politecnico di MilanoInventors: Yuki Matsui, Ken Nakamuro, Franco Zappa, Federica Villa, Rudi Lussana

Patent number: 11422348Abstract: A method for operating a point laser-scanning microscope includes scanning a sample with a focused illumination laser beam; recording a plurality of images by detecting elements being configurable to an intensity mode, in which the recorded images are intensity images gi,j(n) related to photons collected during an entire dwell time of the illumination beam on an individual position n, or to a time-resolved mode, in which the recorded images are time-resolved images gi,jt(n, t), the collected photons being discriminated based on their arrival times to individual detecting elements; calculating a fingerprint image a by summing the plurality of intensity images gi,j(n) over all positions n; estimating shift matrices sx and sy from the intensity images gi,j(n); reconstructing at least one of a time-resolved object function ft and an intensity object function f; and visualizing at least one of a high-resolution time-resolved image ft˜ and a high-resolution intensity image f˜.Type: GrantFiled: January 24, 2019Date of Patent: August 23, 2022Assignees: FONDAZIONE ISTITUTO ITALIANO DI TECNOLOGIA, POLITECNICO DI MILANO, UNIVERSITA' DEGLI STUDI DIGENOVAInventors: Giuseppe Vicidomini, Marco Castello, Giorgio Tortarolo, Alberto Tosi, Mauro Buttafava, Federica Villa, Paolo Bianchini, Alberto Diaspro, Colin J.
