What is electro-optical seeker?

What is electro-optical seeker?

DESCRIPTION: The detection and discrimination of tactical surface targets (land and sea) can be accomplished using a sophisticated electro-optical seeker integrated in a fast moving projectile. Aerothermal survivability extends to the window material used on the projectiles surface as the aperture for the seeker.

What is electro-optical imaging system?

EO/IR (Electro-Optical/Infra-Red) systems are imaging systems used for military or law enforcement applications which include both visible and infrared sensors. Because they span both visible and infrared wavelengths, EO/IR systems provide total situational awareness both day and night and in low light conditions.

How does electro-optical guidance work?

The target image is picked up by the TV camera in the missile. The missile is guided automatically to the target once it is released after lock on. The TV head continuously compares target’s contrast with its surrounding and is guided in this way.

Where are the electro-optical sensors used?

Where are the electro-optical sensors used? Explanation: The electro-optical sensors can be used for position and speed measurement. These devices can operate on high frequencies. Also, it can detect fast-moving objects.

What is the electro-optical effect produced by?

The electro-optic effect (or electrooptic effect) is the modification of the refractive index of a medium, caused by an electric field. It is exploited in Pockels cells, which can be part of electro-optic modulators, and for electro-optic sampling. …

What is electro-optical payload?

Aiding the Military and Defence Sectors Closer to home, ‘electro-optical’ (EO) payloads are being used for several air-, ground- and seaborne military and defence applications such as intelligence, surveillance, target acquisition and reconnaissance (ISTAR) operations.

What is EO IR payload?

The new and lightweight EO/IR payload is said to have unsurpassed maritime surveillance capabilities and has been specially configured for observation from maritime vessels, including small boats, even in the harshest and most challenging environmental conditions.

What is the most common wavelength band which electro optical scanners work within?

Active EO sensors employ coherent sources in the wavelength region from the long-wavelength infrared (around 10 µm) to the atmospheric transmission limit for UV light, around 200 nm.

What sensors can detect the presence of an object that has been moved?

Motion sensors detect the movement of an object and can be used to trigger action (such as illuminating a floodlight or activating a security camera). Proximity sensors as well can detect that an object has come within range of the sensor.

How do EO IR sensors work?

Function. An optical sensor converts light rays into electronic signals. An optical sensor can measure the changes from one or several light beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output.

What is optical remote sensing?

Optical remote sensing makes use of visible, near infrared and short-waveinfrared sensors to form images of the earth’s surface by detecting thesolar radiation reflected from targets on the ground. Different materials reflect and absorb differently at different wavelengths.

What is electelectro-optic (EO)?

Electro-optics (EO), as the name implies, is a combination of electronics and optics. By one definition EO is the science and technology of the generation, modulation, detection, and measurement, or display of optical radiation by electrical means.

What is an electro-optical warfare system?

There are many electro-optical warfare systems, which are analogous to radio frequency (RF) EW systems. These EO EW systems operate in the optical portion of the electromagnetic spectrum. Electro-optics (EO), as the name implies, is a combination of electronics and optics.

What is an EO/IR system?

In the popularly used term “EO/IR,” the EO is typically used to mean visible or laser systems. The use of EO in this context is a misnomer. Actually, almost all “EO/IR” systems are EO systems as defined above.

What is EO (electromagnetic oximetry)?

By one definition EO is the science and technology of the generation, modulation, detection, and measurement, or display of optical radiation by electrical means. Most infrared (IR) sensors, for example, are EO systems.
