What is the multispectral display?
Multispectral display is a form of display that includes data collection from two or more frequencies along the spectrum, such as visible light and infrared energy. There are a number of applications for multispectral display and technology roots lie in satellite display. Many examples can be found on different websites, especially on websites that provide data from orbit satellites. With a multispectral image, you can also display data from infrared, near infrared, radar and other areas of the spectrum. There are a number of different ways to present the data to be meaningful to the observer.
One option is a folded image that combines input from multiple spectra. This image will have a false color, with the spectrum data outside the visible range, presented either by artificial color, such as red or in gray stages. Composite images can show areas of high energy and other things that may be interesting. Multispectral ViewIt can also lead to a number of images showing the same thing at different wavelengths.
As an example of how multispectral display can be used, many archaeologists use this imaging technique routinely in their work. They begin to record data from the visual spectrum and display an object as seen with the naked eye. They then take paintings in the spectrum areas such as an infrared area to reveal things that are otherwise invisible. This technique can be particularly useful for inspecting and restoring the document, as hidden brands can be visible in an infrared plant.
Forensics, geologists, meteorologists and many other sciences require progress to multispectral display to collect important data on the natural world and in artificial objects. The device capable of Tje's type of display differs in size and complexity, including specialized devices mounted on satellites and DAlekohoes that can be intended for specific applications. Learning to interpret multispectral images requires training and time, because people have to learn what different representations mean.
It is important to realize that many multispectral images are presented in false color. For example, composite satellite images can have a lively and striking look, but they do not reflect what the mere eye can see. Colors can be exaggerated or highlighted to emphasize specific features of interest and a note about the image to show whether it is in real or false color.
