Patent number: 11947098Abstract: A multi-focal light-sheet structured illumination system that can be implemented as a part of a commercial fluorescence microscope or a module that is adaptable to fit a number of commercially available microscopes. The system provides simultaneous capture of 2D images from multiple planes within a 3D volume, which are resolved laterally and axially to provide improved resolution along the three dimensions (x,y,z). A Wollaston prism allows several axially-localized high-contrast structured illumination patterns to be generated.Type: GrantFiled: March 29, 2022Date of Patent: April 2, 2024Inventors: Chrysanthe Preza, Ana Doblas, Genaro Saavedra-Tortosa, Manuel Martinez-Corral, Juan Carlos Barreiro

Patent number: 11017546Abstract: A depth detection device includes a stereo image recording device, a scaler and a depth determiner is provided. The stereo image recording device is configured to record a stereo image of a scene, and includes a first optical path for recording a first image of the stereo image, and a second optical path for recording a second image of the stereo image. The first optical path and the second optical path have different lengths. The scaler determines a scaling of the first image or of the second image, by minimizing differing lateral magnification of objects in the scene, and for performing the scaling. The depth determiner determines a depth map of the scene based upon the scaled stereo image.Type: GrantFiled: April 23, 2019Date of Patent: May 25, 2021Assignee: Huawei Technologies Co., Ltd.Inventors: Hector Navarro Fructuoso, Manuel Martinez Corral, Genaro Saavedra Tortosa, Jorge Sola Pikabea, Juan Carlos Barreiro Hervas, Seokmin Hong

Publication number: 20140347628Abstract: The invention relates to a fundus camera that incorporates an integral imaging system for capturing an integral photograph of the fundus. This integral photograph enables projecting a three-dimensional image and generating topographical maps of the fundus. The fundus camera can function plenoptically and thus zoom onto a two-dimensional image generated from the integral photograph. The proposed equipment consists of an optical system for illuminating the fundus and an optical system forming the integral image capture system. This capture system includes an ophthalmoscopic lens, a microlens array and a sensor, and it allows recording, in a single shot, multiple views of the fundus. To improve the resolution of the integral photograph, the capture system has a device that allows displacing the microlens array by a few microns.Type: ApplicationFiled: October 18, 2012Publication date: November 27, 2014Applicants: ASOCIACION INDUSTRIAL DE OPTICA, COLOR E IMAGEN - AIDO, UNIVERSITAT DE VALENCIAInventors: Manuel Martinez Corral, Amparo Pons Marti, Genaro Saavedra Tortosa, Hector Navarro Fructuoso, Raul Martinez Cuenca, Angel Tolosa Ruiz, Natividad Alcon
