Electro-optical systems use EO radiation to create useful output images
Electro-optical imaging systems use EO radiation emitted or reflected by a target to produce a useful output image. Common examples of such systems include thermal imagers and night-vision, or image intensification, systems. Thermal imaging relies on the principle that all objects emit some amount of infrared radiation, which increases in proportion to the temperature of the object. Thermal imaging systems incorporate an infrared radiation detector and convert the information from collected radiation into a format visible to the human eye.
Passive systems are used when the target is likely to have a higher temperature than its surroundings. On the other hand, an active system that incorporates its own energy source may be needed to distinguish a target that is normally in equilibrium with its surroundings. EO/IR (Electro-Optical/Infra-Red) systems are another type of imaging system that consists of both electro-optical and infrared sensors supported by computing architectures.
EO/IR systems provide total situational awareness during the day, night, or in low-light conditions. They are commonly used in military or law enforcement applications and are mounted on aircraft, vehicles, or used at sea or hand-carried. EO/IR systems must be able to identify, track, and assess threats from a distance and in challenging environments. EO/IR technology is also being incorporated into smaller payloads, such as traditional drones, to improve awareness and reduce risk to ground forces.

Imaging
Electro-optical imaging systems use radiation emitted or reflected by a target to produce an output image. Common examples include thermal imagers and night-vision systems. Thermal imaging systems incorporate an infrared radiation detector and convert the collected radiation into a format visible to the human eye. Passive systems are used when the target has a higher temperature than its surroundings, while active systems with their own energy source are used when thermal contrast is required to distinguish a target.
Target Acquisition
Electro-optical systems can be used for target acquisition in military applications, such as a targeting tool for missiles and other projectiles. The emitted radiation is scattered by the target and detected by the projectile as it approaches, providing a more accurate location fix.
Rangefinding
Rangefinding capabilities of electro-optical systems are used in conjunction with target acquisition to determine the distance to a target. This information is crucial for precise targeting and can be achieved through various methods, including thermal imaging and night-vision systems.
Surveillance
Surveillance electro-optical systems are employed for monitoring and security applications, offering wide coverage and long lifespans. They are used in border camera systems, coastal surveillance, vessel traffic monitoring, airport security, power plant protection, and other land missions. These systems can integrate radars, searchlights, day/night cameras, thermal imaging cameras, and optical sensors to provide a comprehensive 360-degree surveillance solution for detecting, evaluating, and tracking multiple targets over long distances. Surveillance electro-optical systems can be customised to meet specific environmental and installation requirements, ensuring tailored solutions for diverse surveillance needs.

Electro-optical sensors convert light or changes in light into electronic signals
Electro-optical sensors are electronic detectors that convert light or changes in light into electronic signals. They can detect electromagnetic radiation from infrared to ultraviolet wavelengths. This means that electro-optical sensors can also act as infrared sensors or IR sensors.
Electro-optical sensors are used in many industries and consumer applications. They are used in flash detection and synchronisation, lights that switch on automatically in low-light conditions, position sensors, and photoelectric sensors that can detect the absence, presence, and distance of objects.
Optical switches are used in thermal methods to vary the refraction index in one leg of an interferometer to switch the signal. They can also be used in MEMS approaches involving arrays of micromirrors that deflect an optical signal to the appropriate receiver. Optical switches are usually used in optical fibres, where the electro-optic effect is used to switch one circuit to another.
Electro-optical sensors are used in smartphones to adjust screen brightness and in smartwatches to measure the wearer's heartbeat. They are also used in the energy field to monitor structures that generate, produce, distribute, and convert electrical power.
