What Are Multispectral Cameras?
Multispectral cameras are imaging devices designed to capture image data at specific frequencies across multiple distinct bands of the electromagnetic spectrum. Unlike conventional cameras that capture only visible light, multispectral cameras can obtain additional information the human eye cannot see. Multispectral cameras are often customized for individual applications, notably in terms of the spectral bands utilized.
Multispectral photographs are either taken with specialized cameras that use filters to separate these wavelengths or with equipment sensitive to a specific wavelength range, such as light from infrared and ultraviolet frequencies (for example), which are invisible to the human eye.
Key Market Statistics and Drivers Behind Them
The global multispectral camera market was valued at USD 1,025.16 million in 2022 and is expected to reach USD 2,400.33 million with a CAGR of 8.9% during the forecast period. Growing R&D (research and development) activities are a major factor in the market’s expansion. For instance, with regard to its Thermal by FLIR program for small unmanned aircraft systems (sUAS), Teledyne FLIR has made significant progress.
