20090116108 | Lenticular Autostereoscopic Display Device and Method, and Associated Autostereoscopic Image Synthesizing Method - An autostereoscopic display device comprises a matrix display screen having a horizontal axis and a vertical axis, and a lenticular array arranged in front of the display screen and having a lenticular axis that is inclined in relation to the vertical axis. The display device emits an image comprising a set of three-dimensional pixels, each three-dimensional pixel including a plurality of viewpoints of a corresponding image pixel of a scene to be displayed. For each three-dimensional pixel, the plurality of viewpoints of each corresponding image pixel are encoded along a horizontal axis, while color components associated with each viewpoint of each image pixel are encoded in separate rows generally aligned along an encoding axis that is substantially parallel to the lenticular axis. | 05-07-2009 |
20090295909 | Device and Method for 2D-3D Switchable Autostereoscopic Viewing - An autostereoscopic viewing device switchable between a two-dimensional mode and a three-dimensional mode. The device generally includes a matrix viewing display, and a set of two lenticular networks or arrays, one of which is called a converting lenticular network or array. The lenticular networks or arrays are arranged in front of the viewing display. The converting lenticular array is designed to receive and optically process a raster or matrix image emitted by the viewing display. The autostereoscopic viewing device further includes means for varying a plurality of distances between a first lenticular array and a second lenticular array or the viewing display. The invention is useful in particular for computer displays or three-dimensional television sets. | 12-03-2009 |

20150042778 | METHOD AND OPTICAL DEVICE FOR SUPER-RESOLUTION LOCALIZATION OF A PARTICLE - A super-resolution microscopy method includes forming an image of an emitting particle in a detection plane of a detector by a microscopy imaging system and correcting, by a wavefront-modulating device, at least some of the optical defects present between the emitting particle and the detection plane. The method further includes introducing, via the wavefront-modulating device, a deformation of the wavefront emitted by the emitting particle, of variable amplitude, allowing a bijective relationship to be formed between the shape of the image of the emitting particle in the detection plane and the axial position of the emitting particle relative to an object plane that is optically conjugated with the detection plane by the microscopy imaging system. The method further includes controlling the amplitude of the deformation of the wavefront by controlling the wavefront-modulating device, as a function of the given range of values of the axial position of the particle. | 02-12-2015 |
