Infrared arrays are detectors sensitive to infrared energy used in various tasks such as imaging, astronomy, and security. Multiple detectors can be mounted together for simultaneous operation, providing detailed information. Firefighters and police use this technology to identify sources of infrared energy. Astronomers use it to observe distant objects. Sensitivity of detectors can vary, and manufacturers offer a range of options to meet different consumer needs.
An infrared array is a collective of detectors sensitive to energy in the infrared range of the spectrum. Such devices can be used in a variety of tasks where the ability to collect data from infrared sources may be important. These include infrared imaging to aid law enforcement, telescopes for astronomical observations, and security systems. Manufacturers of these products may have a range of options available to meet different consumer needs.
In an infrared array design, detectors sensitive to a range of wavelengths can be mounted together to operate simultaneously. When the user activates the system, it acquires multiple images simultaneously, generating a variety of information. The high degree of sensitivity can enable sharp resolution and detailed information. Operators can split the results if needed to get a look at a narrower band of the spectrum.
Infrared array imaging equipment is used by people such as firefighters and police officers to identify sources of infrared energy at a scene. In a fire, for example, a camera trained on a house can show whether living things are still inside. Similarly, police responding to a scene who want to gather more information about what is happening can aim an infrared array to count the number of people present and see what they are doing. This can help them identify hostages, innocent people, armed individuals and other persons of interest who may be present, but in hiding.
Astronomers use this technology to make observations in the infrared area of the spectrum, which can provide useful data on near and distant objects. Stars and other bodies in space emit energy in a variety of wavelengths. Sensitized devices that look for different areas of the spectrum can help people learn about the properties of the objects they observe. Researchers can discover the position, size, shape and composition of distant stars and other phenomena of interest with an infrared array.
The sensitivity of the detectors in the array can vary. When there is a need to observe across the entire infrared spectrum, multiple detectors can be used to achieve the best resolution, rather than attempting to build a single detector to accommodate that need. Some designs can be modified and adapted to add or replace detectors if it becomes necessary to make observations in a different range. Companies working on infrared array technology are also constantly refining their products to meet the ever-changing needs of customers.
