Scientists have developed infrared vision technology: mosquitoes, some fish and snakes have it

Scientists from the Center of Competence of NTI “Sensorica” ​​on the basis of the National Research University “MIET” have developed a technology for the production of infrared photodetector matrices. With the help of the new development, the cameras will be able to see in the infrared range like mosquitoes, certain types of fish, and snakes.

According to university experts, the new matrix will allow cameras to see in the infrared range and distinguish objects like mosquitoes or snakes. Devices with such a matrix will make it possible to distinguish objects against a cool background, including in conditions of fog, dust, and behind small opaque obstacles.

Engineers have created a photo matrix based on indium-gallium-arsenic (InGaAs) heterostructural compounds on an indium phosphide substrate. In their opinion, this compound has more functionality than silicon-based matrices, which are widespread in the world.

Heterostructure is a sequence of thin layers that are grown one after another. The substrate itself consists of such layers. On this substrate, a matrix with a resolution of 516×625 pixels is formed, the size of one pixel is less than 20 μm.

Optical materials such as receiver windows, lenses, or various coatings also work in the infrared wavelength range. Therefore, we can use these parts in the design of devices to significantly reduce the final cost.

The developers also believe that the new technology will allow Russia to stand on a par with the world leaders in the production of photosensors. In addition to being used in night vision devices, this technology can be applied in microelectronics and medicine.
