Patent number: 11830901Abstract: An optical system (400) including a microlens array (104), an image sensor (108) and a PCB (206). The microlens array (104) is bonded to the image sensor (108) with glue lines (804) or glue drops (802) dispensed around the non-active area (404) of the microlens array (104). The image sensor (108) may be bonded to the PCB (206) with a layer of adhesive material (502) applied only on a central region of the image sensor (108). Alternatively, the image sensor can rest onto a thermally conductive resin layer (109) placed over a stiffener (207), and the image sensor can be attached to the PCB (206) by one or more glue drops (111) or glue lines (113) arranged on at least one side of the image sensor (108) or by an adhesive layer (115) laterally surrounding the image sensor (108). The optical system (400) solves the problem of misalignment between the image sensor and the microlens array caused by changes in temperature.Type: GrantFiled: January 16, 2021Date of Patent: November 28, 2023Assignee: PHOTONIC SENSORS & ALGORITHMS, S.L.Inventors: Jorge Blasco, Ivan Virgilio Perino, Leticia Carrión, Javier Grandia, Francisco Alventosa

Patent number: 11456326Abstract: A plenoptic camera for mobile devices is provided, having a main lens, a microlens array, an image sensor, and a first reflective element configured to reflect the light rays captured by the plenoptic camera before arriving at the image sensor, in order to fold the optical path of the light captured by the camera before impinging the image sensor. Additional reflective elements may also be used to further fold the light path inside the camera. The reflective elements can be prisms, mirrors or reflective surfaces of three-sided optical elements having two refractive surfaces that form a lens element of the main lens. By equipping mobile devices with this plenoptic camera, the focal length can be greatly increased while maintaining the thickness of the mobile device under current constraints.Type: GrantFiled: June 14, 2018Date of Patent: September 27, 2022Assignee: PHOTONIC SENSORS & ALGORITHMS, S.L.Inventors: Leticia Carrion, Jorge Blasco, Francisco Clemente, Francisco Alventosa, Arnau Calatayud, Carles Montoliu, Adolfo Martinez, Ivan Perino

Patent number: 11099304Abstract: A microlens array that corrects the problems caused by aberrations and non-paraxiality of microlenses is provided. The microlens array has a plurality of microlenses tilted a tilting degree (?, ?) depending on the position of the microlens in the microlens array. Simultaneously, or alternatively, the distances Pul(i) between optical centres (Pi, Pi?1) of adjacent microlenses depend on their positions in the microlens array. Both these distances Pul(i) and the tilting degrees (?, ?) are dependent normally increasing upon the distance to the center of the microlens array. The size of the microlenses may also increase with the distance to the center of the microlens array. An opaque layer may also be applied covering the edges of adjacent microlenses.Type: GrantFiled: December 5, 2016Date of Patent: August 24, 2021Assignee: PHOTONIC SENSORS & ALGORITHMS, S.L.Inventors: Jorge Vicente Blasco Claret, Carles Montoliu Alvaro, Arnau Calatayud Calatayud, Leticia Carrion, Adolfo Martinez Uso

Patent number: 10832429Abstract: A device and method for obtaining depth information from a light field is provided. The method generating a plurality of epipolar images from a light field captured by a light field acquisition device; an edge detection step for detecting, in the epipolar images, edges of objects in the scene captured by the light field acquisition device; for each epipolar image, detecting valid epipolar lines formed by a set of edges; and determining the slopes of the valid epipolar lines. In a preferred embodiment, the method extend the epipolar images with additional information of images captured by additional image acquisition devices and obtain extended epipolar lines. The edge detection step calculates a second spatial derivative for each pixel of the epipolar images and detects the zero-crossings of the second spatial derivatives.Type: GrantFiled: December 20, 2016Date of Patent: November 10, 2020Assignee: PHOTONIC SENSORS & ALGORITHMS, S.L.Inventors: Jorge Vicente Blasco Claret, Carles Montoliu Alvaro, Arnau Calatayud Calatayud, Leticia Carrion, Adolfo Martinez Uso
