DARPA initiates a program to create a multispectral advanced night vision system for military purposes – envision. In the future, it will replace bulky night vision systems with light and comfortable glasses that resemble the usual ones.
The first night vision systems were developed on the eve of the Second World War, but their use began in the 60s. Despite numerous improvements over the past decades, night vision technology is still far from perfect. The main disadvantage of these devices is their large size and weight, despite the fact that the "picture" that the user sees is still a third of what is visible to the naked eye.

The envision program is supposed to use the latest achievements in the field of photonics and optical materials in order to replace complex electronics with a single flat lens. In particular, planar optics, new materials for detecting light and technologies for its interaction with matter will be used. In addition, during the implementation of the program, specialists will consider the possibility of using thin materials to directly transfer photons from the infrared region of the spectrum to the visible one, eliminating the traditional optical processing system.
