El programa ENVision utilizar\u00e1 avances recientes en \u00f3ptica plana y materiales de transducci\u00f3n para desarrollar nuevos sistemas de visi\u00f3n nocturna (NV) de visi\u00f3n directa.\u00a0Estos sistemas muestran un mayor campo de visi\u00f3n (FOV) y un mejor acceso visual a trav\u00e9s de bandas infrarrojas (IR), todo contenido en un factor de forma de anteojos de bajo torque.<\/p>\n
The US Defense Advanced Research Projects Agency (DARPA) has\u00a0chosen<\/a>\u00a0research teams for the enhanced night vision in eyeglass form (ENVision) programme.<\/p>\n Of the ten industry and university teams that were selected, five teams were picked for the two technical areas.<\/p>\n The ENVision programme will use recent advances in planar optics and transduction materials to develop new direct-view night-vision (NV) systems.<\/p>\n These systems showcase an increased field of view (FOV) and improved visual access across infrared (IR) bands, all contained in a low-torque eyeglass form factor.<\/p>\n According to DARPA, current NV systems are heavy, which burden the user and limit the wearer\u2019s agility, as well as lead to chronic injury due to prolonged use.<\/p>\n Physical Sciences, Raytheon Technologies Research Center, SRI International, the University of California-San Diego, and the University of Washington are the five teams selected for the first technical area.<\/p>\n Performers under the first technical area will develop multi-band, wide FOV planar optics and planar image intensifiers to showcase advanced NV systems, imposing near-zero torque on the wearer.<\/p>\n In the second technical area, teams from Raytheon BBN, Stanford University, the University of Central Florida, the University of Melbourne, and the University of Pennsylvania were selected.<\/p>\n These teams will explore new methods to amplify photonic up-conversion processes from any IR band to visible light, to allow for future \u2018intensifier-free\u2019 NV systems.<\/p>\n DARPA Defense Sciences Office ENVision programme manager Rohith Chandrasekar said: \u201cThe teams in the first technical area are developing technologies that could drastically reduce the bulk and volume of objective, intensifier, and eyepieces of night-vision systems.<\/p>\n \u201cTeams in the second technical area are exploring ways to directly upconvert and amplify light, from the infrared to the visible, using new materials and up-conversion processes.<\/p>\n \u201cThese efforts could potentially lead to all-optical night vision systems in the future, without the need for image intensifiers.\u201d<\/p>\n In December 2021, DARPA\u2019s OFFSET programme conducted its\u00a0final field experiments<\/a>, which involved deploying autonomous air and ground vehicles to test mission capabilities.<\/p>\n
