20120013706 | INFRARED WIDE FIELD IMAGING SYSTEM INTEGRATED IN A VACUUM HOUSING - The present disclosure relates to a compact wide field imaging system for the infrared spectrum range, the system including a vacuum housing with a porthole, a cooled dark room arranged inside the vacuum housing and provided with an opening referred to as a cold diaphragm, an infrared detector arranged inside the cooled dark room, and a device for the optical conjugation of the field rays with the detector. In the system, the optical conjugation device does not include any element located outside the vacuum housing, and includes at least one cold lens located inside the cooled dark room, the pupil of the optical conjugation device coinciding with the cold diaphragm. | 01-19-2012 |

20140055606 | Method and Device for Range Imaging - A method for range imaging allows determining respective distances to multiple objects, based on a single image. The image is captured through a component having a transmittance function of which the Fourier transform is inscribed on a circle within a plane of spatial frequencies. A Fourier transform of the captured image is calculated in order to obtain a total spectrum for the image content. The distance to each object is then calculated based on several homothetic superimpositions of a reference spectrum with the total spectrum, so that said reference spectrum coincides with a portion of the total spectrum each time. | 02-27-2014 |
20140111651 | IMAGING SYSTEM COMPRISING A FRESNEL LENS - The imaging system for imaging field rays comprises a detection surface, a device for focusing the field rays with said detection surface, and a diaphragm. Said device comprises a Fresnel lens comprising a first dioptre, the non-plane surface of which, called the active zone, makes it possible to focus the field rays towards said detection surface, and said diaphragm allows controlled distribution of the field rays over said active zone. | 04-24-2014 |
