SWIR spectral bands can be used to map and quantify how much crop residue is left behind, predicting the soil quality for future crops. WorldView-3's spectral bands allow for unique mineral identification and chemical measurements.
What does SWIR mean in remote sensing?
short-wave infrared
What are SWIR cameras?
Shortwave infrared (SWIR) imaging introduces a broad range of possibilities in industrial and scientific applications. Traditional machine vision systems using CCD and CMOS image sensors can effectively capture images within the visible spectrum of light.30 Apr 2019
What is SWIR?
Short-wave infrared (SWIR) defines a specific wavelength range over which optical and electronic components are designed and coated. SWIR imaging offers a number of advantages compared to visible when used for inspection, sorting, surveillance, quality control, and host of other applications.
What is SWIR imaging?
Short-wave Infrared imaging (SWIR) is an advanced technique, used for producing images based on radiation in the region of the electromagnetic spectrum invisible to the naked eye.Short-wave Infrared imaging (SWIR) is an advanced technique, used for producing images based on radiation in the region of the electromagnetic spectrum invisible to the naked eye.13 Aug 2020
What is SWIR spectrum?
Short Wave IR (SWIR) is a subset of the infrared band in the electromagnetic spectrum, covering the wavelengths ranging from 1.4 to 3 microns. This wavelength is not visible to human eyes and as a result can often offer a better image than what is achievable with visible light imaging.
What is SWIR imagery?
Short-Wave Infrared Satellite Imagery. Employing valuable sensors in order to see beyond the capabilities of the human eye.
What can SWIR detect?
SWIR has the capability to detect heat even though it's not as sensitive as MWIR (midwave infrared) and LWIR (longwave infrared), which can detect low temperatures.
How do SWIR cameras work?
Shortwave infrared is typically defined as light in the 0.9 - 1.7 μm wavelength range. Wavelengths within the SWIR band interact with objects just as they do with visible light. Photons in this wavelength are reflected or absorbed by objects, allowing for high resolution imaging with strong contrast.30 Apr 2019
What is the difference between SWIR and NIR?
Typically we define near infrared (NIR) from 780 nm to 1400 nm and shortwave infrared (SWIR) from 1400 nm to 3000 nm. NIR and SWIR wavelengths aren't visible to human eyes and have less energy than UV and visible wavelengths, but the light still interacts with objects.
What are SWIR cameras used for?
SWIR imaging is used in a variety of applications including electronic board inspection, solar cell inspection, produce inspection, identifying and sorting, surveillance, anti-counterfeiting, process quality control, and much more.
