What does EO IR mean?
Electro-Optical and Infrared Sensors (EO/IR)
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 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 the minimum range of IR sensor?
These sensors are good for detection between 100cm-500cm (1-5 meters / 3-15 feet). The long range makes them a good alternative to sonar sensors.
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.
Where is IR sensor used?
IR sensors are now widely used in motion detectors, which are used in building services to switch on lamps or in alarm systems to detect unwelcome guests. In a defined angle range, the sensor elements detect the heat radiation (infrared radiation) that changes over time and space due to the movement of people.
What is EO imaging?
EO IMAGERY ARE PHOTOGRAPHIC STILLS CAPTURED WITH AN ELECTRO-OPTICAL SENSOR (A HIGH-RESOLUTION CAMERA EQUIPPED WITH A TELEPHOTO ZOOM LENS) THAT DETECTS THE MAGNITUDE AND COLOR OF EMITTED OR REFLECTED LIGHT AND RECORDS THE INFORMATION IN THE FORM OF PIXELS.
What is the maximum range of IR?
There is no universally accepted definition of the range of infrared radiation. Typically, it is taken to extend from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 millimeter (mm). This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz.
What is IR proximity sensor?
An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in robots).
Can IR sensor measure distance?
Infrared sensors work on the principle of reflected light waves. Infrared sensors are also used to measure distance or proximity. The reflected light is detected and then an estimate of distance is calculated between sensor and object.
What is an EO sensor?
Electro-optic sensors. The Electro-optic (EO) sensor is a traditional TV camera using the visual spectrum of 390 to 700 nm. It senses the reflected energy the frequency of which produces a color. However, the sensor requires a light source to provide the image. EO systems are more sensitive than the eye and with some processing can provide images…
What is the range of IR sensors?
Maximum range of IR sensor is. 2.8V at 15cm to 0.4V at 150cm with a supply voltage between 4.5 and 5.5 VDC. It is depend on which type of IR sensor you use and how you use.
What is a motion detector?
A motion detector is a device that detects moving objects, particularly people. Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
