Electro Optics and Infrared Sensors on Gyro Stabilized Gimbals

The electro-optical/infrared (EO/IR) sensors on gyro stabilized gimbals play a critical defense role on land, in the air and at sea.ir electro optics: two-axis control These sophisticated systems enable warfighters to see, track and engage enemy threats, even in total darkness or through obscurants like smoke and fog.

Unlike visible light cameras, which require a minimum of light to form an image, IR sensors detect thermal radiation and create images based on temperature differences.ir electro optics: two-axis control This allows them to operate in complete darkness and through fog, smoke and haze.

Many different EO/IR technologies are available, each designed for specific targets and missions.ir electro optics: two-axis control For example, missile launch detection may depend on the very high temperatures of the exhaust plume. The selection of a spectral band for this type of mission may also be influenced by environmental conditions, such as humidity or wind speed.

IR sensor technology has numerous civilian applications, too.ir electro optics: two-axis control For example, IR cameras can identify areas of temperature differences, which can be helpful in industrial maintenance (to find leaks or overheating machinery) and medical (to monitor inflammation or circulation). Some types of IR sensors are also capable of detecting gases that absorb or emit infrared radiation. This capability is useful for locating gas leaks in pipes or storage tanks.

A specialized type of IR camera is used for firefighting, as it can spot flames and hot spots in the center of a fire or locate people trapped or unconscious in a room. Another common use of IR technology is in security screenings, where it can be used to detect elevated body temperature, a common symptom of certain infectious diseases.

EO/IR sensors can be mounted on aircraft, unmanned aerial vehicles (UAVs) or satellites for surveillance, reconnaissance, target acquisition and weather observation. They can operate in a variety of environmental conditions, including fog, smoke, haze and rain. They can also operate at higher altitudes to achieve a longer line of sight, which is important for military operations.

In addition to their military and commercial uses, gyro stabilized EO/IR gimbals are commonly used on drones for industrial inspection, aerial surveying, search and rescue, counter-UAS and anti-drone defense and environmental monitoring. They are also a vital component of UAVs used for ISTAR (Intelligence, Surveillance, Targeting and Reconnaissance) missions.

The EO/IR sensors on gyro stabilized UAVs and satellites need powerful, reliable and precise motors to provide precise motion control. This series of videos explores the technologies, challenges and options for selecting the right motor for EO/IR platforms. From choosing the proper motor size and optimizing form factor to addressing cogging and torque ripple, each video covers the key factors that influence motor selection for EO/IR applications.
