What is the difference between EO and IR?
What is the difference between EO and IR?
The distinction between the two is working wavelength or spectral quantum efficiency: A CCD can sense light in the near ultraviolet (UV) down to near IR, which is often called the electro-optic (EO) spectral band, and IR detectors can sense the IR spectrum.
What is electro optic imaging?
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 do electro-optical sensors work?
Electro-optical sensors typically combine light detection technology with software that controls multiple light sources, bombarding a target with different light waveforms at different angles. The reflected light waves then are analyzed to identify characteristics of the detected object.
Is EO and IR radar?
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. In the popularly used term “EO/IR,” the EO is typically used to mean visible or laser systems.
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.
Is IR sensor An optical sensor?
Optical sensors based on surface acoustic waves and infrared (IR) mechanisms are commonly used to detect a user’s touch.
What are electro optics used for?
Electro-optical sensors are used whenever light needs to be converted to energy. Because of this, electro-optical sensors can be seen almost anywhere. Common applications are smartphones where sensors are used to adjust screen brightness, and smartwatches in which sensors are used to measure the wearer’s heartbeat.
What are electro-optic sensors?
Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. These sensors are able to detect electromagnetic radiation from the infrared up to the ultraviolet wavelengths.
Which one is electro-optical device?
Devices Based on the Electro-optic Effect Mostly, one uses the linear electro-optic effect (Pockels effect), and less often the Kerr effect (quadratic electro-optic effect). The most important kind of electro-optic devices is the electro-optic modulator, containing a Pockels cell as its core element.
What sensor does FLIR use?
Forward-looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.
What is EO seeker?
TECHNOLOGY AREA(S): Weapons. OBJECTIVE: Develop a compact electro-optical seeker that provides high resolution, high sensitivity, and high update rates (low dwell times) for the detection and discrimination of tactical surface targets at extremely high closure rates.
Where is electro optical sensor used?
What is electro-optic material?
Non-crystalline, solid electro-optical materials have generated interest because of their low cost of production. These organic, polymer-based materials are also known as organic EO material, plastic EO material, or polymer EO material. They consist of nonlinear optical chromophores in a polymer lattice.
What is electro-optic 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 the difference between FLIR and thermal?
FLIRs make pictures from heat, not visible light. Heat (also called infrared, or thermal, energy) and light are both parts of the electromagnetic spectrum, but a camera that can detect visible light won’t see thermal energy, and vice versa.
Can FLIR see through walls?
Thermal imaging devices can’t “see” through walls. But pointing a thermal camera at a building still reveals sensitive information about what’s going on inside. Thermal cameras read the heat radiating off of an object.
What is the function of seeker in missile?
seeker comprises (1) the dome to protect the seeker from aerodynamic forces and the weather; (2) an optical system to focus the incident scene flux onto the detector; (3) a stabilised gimbal system to point the optical path towards the identified target and to minimise jitter in the image; (4) an IR detector to collect …
What are the key features of an EO/IR sensor?
These include target-background contrast and intensity of the illumination source (for bands where reflected light is dominant), target temperature (for bands where emitted radiation dominates), visual range, and operating altitude of the platform on which the EO/IR sensor is integrated.
How does EO/IR detect missile launches?
For example, missile launch detection depends on the very hot missile exhaust, which produces significant radiation in the ultraviolet (UV) spectral region. The band choice is also influenced by the vagaries of atmospheric transmission and scattering. EO/IR missions divide roughly into dealing with point targets and extended fully imaged
What is EO/IR Distributed Aperture System?
A multi-sensor targeting and surveillance system that enables aircrews to detect, acquire, auto-track and identify targets at long ranges. Northrop Grumman’s EO/IR distributed aperture system (DAS) provides a 360 degree, protective sphere of situational awareness for the F-35 Lightning pilot.
