Today, specialists from the University of Illinois have demonstrated and tested a new unique filter for night and laser vision devices based on the special shape of the graphene structure. This filter, previously developed in conjunction with specialist engineers from the US Air Force camp, was created to improve traditional night and laser vision systems for use in everyday army practice, when soldiers need to navigate in a space filled with gas, smoke or some chemicals. An article with this development has already appeared in the journal Science & Applications.
The development team, led by Professor Sung Vo Nam, managed to bring to mind the primary graphene structure that formed the basis of this light filter – it is worth noting that it is an integrated system for changing a special color matrix, through which the user can switch between the identification of certain chemicals in space. This also includes the ability to switch to smoke and gas mode, which will become very popular among the US Army.
The main advantage of this graphene filter is that the operator can control the change of its modes directly during a change of situation using the built-in switch system, which is a very convenient and rational way of orientation in space. Especially when it comes to critical situations, when the count goes for a split second.
The graphene structure, presented by the team of Professor Nam, is replete with some innovations – in particular, a slightly changed structure of absorption and reflection of light, so that the filter matrix can be adjusted in a very flexible way. At the moment, the development team is working on improving the finished engineering sample of this filter, however, preliminary test results can already boast of a high efficiency device with an integrated system of this type.
