Electro-Optical Infrared Two-Axis Solutions
Infrared is invisible to the human eye, but it can detect the heat signature of an object.electro infrared: two-axis solutions This makes it useful for detecting and tracking objects, especially in low light conditions. It also allows us to see cool, distant objects in the universe such as planets, stars, and nebulae.
Electro-optic infrared (EO/IR) systems are used to capture, process, and display image data – often on board unmanned aerial vehicles such as drones or helicopters.electro infrared: two-axis solutions These airborne systems are commonly used for homeland security, military, and law enforcement applications.
EO/IR sensors provide real-time situational awareness by combining thermal imaging with visible light images.electro infrared: two-axis solutions This helps ensure that operators are aware of the whole scene – including people, animals, vehicles, and objects. These systems can also be used for surveillance, reconnaissance, and search and rescue missions.
The human eye can’t see infrared, but these wavelengths are essential to the operation of many devices, such as televisions and computers.electro infrared: two-axis solutions They are also the most important wavelengths for observing biological events, such as a person’s heartbeat. IR cameras are also used to measure the performance of industrial machinery, such as factory robots. They can detect mechanical anomalies such as vibration, overheating, and power failures.
An EO/IR sensor is made up of an array of photoconductive or photovoltaic detector elements, each with its own processing electronics. This is what makes these sensors so versatile and inexpensive. Most modern IR cameras use focal plane arrays that combine detector and processing components on the same chip, which reduces the size of the system. They can be configured with different pixel sizes and resolutions, which determines the sensor’s sensitivity.
Depending on the physics involved in the detector, an IR system can be classified as either thermal or quantum. The former relies on the pyroelectric effect, which causes a change in polarization of crystals when they are heated. This change is detected by observing the buildup of surface charge on the crystal’s substrate. The latter uses the bolometric effect, which is the generation of an electrical signal from a temperature gradient in a semiconductor. The bolometric signal is then processed to determine the temperature.
A key advantage of IR is that it can distinguish organic compounds from one another. The spectra of each pure substance have unique absorption bands. In the region of 7-11 microns (1430-910 cm-1) for example, no two organic compounds have identical absorption spectra. This means that, provided a chemist has a copy of the spectrum, they can identify an unknown pure compound by its unique fingerprint.
Infrared has been shown to improve cardiovascular health by boosting the production of nitric oxide in the blood vessels, which prevents blood clotting and clumping. Nitric oxide also reduces oxidative stress and regulates blood pressure. It has also been shown to speed up wound healing and increase tissue elasticity.
