Patent number: 11512836Abstract: The illumination module for emitting light (5) can operate in at least two different modes, wherein in each of the modes, the emitted light (5) has a different light distribution. The module has a mode selector (10) for selecting the mode in which the module operates, and it has an optical arrangement. The arrangement includes—a microlens array (LL1) with a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P (P1);—an illuminating unit for illuminating the microlens array (LL1). The illuminating unit includes a first array of light sources (S1) operable to emit light of a first wavelength L1 each and having an aperture each. The apertures are located in a common emission plane which is located at a distance D (D1) from the microlens array (LL1). In a first one of the modes, for the lens pitch P, the distance D and the wavelength L1 applies P2=2·L1·D/N wherein N is an integer with N?1.Type: GrantFiled: January 24, 2017Date of Patent: November 29, 2022Assignee: ams Sensors Singapore Pte. Ltd.Inventors: Markus Rossi, Martin Lukas Balimann, Mai-Lan Elodie Boytard, Bassam Hallal, Daniel Pérez Calero, Julien Boucart, Hendrik Volkerink

Patent number: 10509147Abstract: An apparatus for producing structured light comprises a first optical arrangement which comprises a microlens array (L1) comprising a multitude of transmissive or reflective microlenses (2) which are regularly arranged at a lens pitch P and an illumination unit for illuminating the microlens array. The illumination unit comprises an array (S1) of light sources (1) for emitting light of a wavelength L each and having an aperture each, wherein the apertures are located in a common emission plane which is located at a distance D from the microlens array. For the lens pitch P, the distance D and the wavelength L, the following equation applies P2=2LD/N, wherein N is an integer with N?1. High-contrast high-intensity light patterns can be produced. Devices comprising such apparatuses can be used for depth mapping.Type: GrantFiled: January 26, 2016Date of Patent: December 17, 2019Assignee: AMS SENSORS SINGAPORE PTE.

Patent number: 10497141Abstract: A brightness image of a scene is converted into a corresponding frequency domain image and it is determined whether a threshold condition is satisfied for each of one or more regions of interest in the frequency domain image, the threshold condition being that the number of frequencies in the region of interest is at least as high as a threshold value. The results of the determination can be used to facilitate selection of an appropriate block matching algorithm for deriving disparity or other distance data and/or to control adjustment of an illumination source that generates structured light for the scene.Type: GrantFiled: December 23, 2016Date of Patent: December 3, 2019Assignee: AMS SENSORS SINGAPORE PTE. LTD.Inventors: Chi Zhang, Alireza Yasan, Hendrik Volkerink

Patent number: 10298570Abstract: Optoelectronic systems include an array of optoelectronic modules and a computational unit. The array of optoelectronic modules and the computational unit are operable to collect data of a user of the optoelectronic system. The data can be used, for example, to authenticate the identity of the user by being used in multiple user authentication protocols. In some instances, facial recognition data can be augmented with three-dimensional data of the user and can be combined with iris recognition data to authenticate the identity of the user. Such optoelectronic systems can comprise hardware authentication systems external to auxiliary devices such as tablet computers and laptop computers.Type: GrantFiled: March 2, 2017Date of Patent: May 21, 2019Assignee: ams Sensors Singapore Pte. Ltd.Inventors: Yibin Tian, Hendrik Volkerink

Publication number: 20190107627Abstract: The present disclosure describes an optoelectronic system and methods for efficiently capturing three-dimensional data. The optoelectronic system includes a three-dimensional imaging module and a distance measuring module. Data collected via the distance measuring module is used to collect three-dimensional data, such as three-dimensional maps or other representations of three-dimensional objects. Further, the approach can be extended to multiple regions of interest, and can be applied to the acquisition of biometric data.Type: ApplicationFiled: February 16, 2017Publication date: April 11, 2019Inventors: Yibin Tian, Hendrik Volkerink
