Imaging Sensor Technology in the Modern Battlefield

Uncertainty and instability have been growing in the world and in our immediate global vicinity. Optics and photonics are some of the key technologies in gathering intelligence from a demanding battlefield. Optical imaging sensors are needed for reconnaissance and for creating a situational awareness. One of the most used passive imaging technologies are thermal imaging, image intensifying and hyperspectral imaging.

Aerial vehicles optically reconnaissance the position and movements of opposing forces. As passive sensors, imaging sensors do not reveal their position to the enemy. Detection of camouflaged targets can be improved by utilizing the correct spectral window or selected wavelengths to distinguish them from the terrain.

Passive imaging unattended ground sensors placed in the terrain wait in a sleep mode and wake up when they detect movement in their environment. By using optical pattern recognition, information on the type, number and direction of the targets can be transmitted over wirelessly to a communication network.

Advanced sensors for dismounted infantry

Frontline scouts use imaging sensors which utilize different technologies. Using thermal imaging technology, targets can be detected 24/7 from several kilometers away. Modern targeting equipment such as the Senop LISA and Senop LILLY, use satellite navigation, inertial sensors, and laser-based ranging to determine the exact coordinates of the target and transmit them along a communications network to the battle command center. 

Dismounted soldiers use Image Intensifier technology when operating in the dark battlefield. This technology is optimal for a regular soldier, providing small size, low power consumption and high image resolution. The modern weapon sights are equipped with added intelligence, reducing the mental burden on the fighter. For example, the Senop AFCD TI intelligent sight uses image fusion and thermal imaging for easier target acquisition. The gunner measures the distance to the target and tracks moving target 2-4 seconds. Ballistic computer automatically calculates elevation, lead angle and the gunner will get the predicted aiming crosshair to the display.

Sensors for armored vehicle use

Armored ground vehicles have an ever-increasing number of different imaging sensors like the Senop HUSKY camera. Due to heavy armoring, visibility out of the vehicles is very limited. Information about the surrounding environment is provided by cameras placed on different sides of the vehicles, but also by a drone flying over.

When driving in the dark, conventional driving lights cannot be used as they expose your location to the opponent kilometers away. Utilizing the image intensifier technology, operating big vehicles is possible in mere starlight. Even thermal cameras are adapted in vehicles for driving aid, due to falling costs of the TI technology. For example, the Patria AMV-vehicles battle management and aiming of the main weapons are carried out by combining different sensor technologies.

The DSEI 2023 exhibition in London from September 12 to 15, offers an excellent opportunity to see and learn more about these devices firsthand from our team.
