Infrared

Overview

Infrared has longer wavelength than visible light (red). The light in the range from 0.75㎛ to 1000㎛ electromagnetic waves are categorize as infrared.
The categorization of infrared ranges are NIR (below 1.4㎛, Near Infrared), SWIR (1.4~3㎛, Short-Wavelength Infrared), MWIR (3~5㎛, Mid-Wavelength Infrared), LWIR (8~14㎛, Long-Wavelength Infrared), and FIR (longer than 20㎛, Far Infrared).
This categorization is based on atmospheric transmitting characteristics of infrared light, which is very useful for observation owing to its high transmittance. User can select the range among different infrared bands according to the purpose of their system.

Importance of Thermal Image

Commercial / Civilian
Variety of uses in field of earth exploration, disaster prevention and astronomical observation in commercial / civilian.
Earth exploration
Research the variation of the weather regarding the evaporation of water vapor and soil moisture by using calibration of infrared images from various wavelength bands of infrared.
Environment
Research the status of biological resources or mineral reserves, exploration, marine resources and ocean currents.
Disaster prevention
Thermal infrared images can find the origin of forest fires or volcanic eruptions. Research the oil spill detection and monitoring red tides if different of IR band information are collected.
Industry and daily life
Applicable to building maintenance and security systems
[Military]
There is very important to detect the thermal image of infrared wavelength band of in the field of the military. Once using the infrared image and visible light image, it can improve detecting performance and maximize reliability. In addition, the infrared observation is able to detect the heat of the target itself, the infrared imaging is possible for poor condition during the night and is effective for continuous monitoring all day and night
