Infrared Technology in Medicine

 Infrared radiation was discovered by the British scientist William Herschel.1800Year first discovered,Infrared light is just like visible light; both are forms of electromagnetic waves.,The difference lies solely in the wavelength.,It travels at a speed in a vacuum300,000km/s,The wavelength range is:0.72μm-1,000μm.Infrared is also known as a热线,Infrared radiation, also known as thermal radiation.,For a thermal radiator, its wavelength λ is related to its temperature.TBetween follows the Wien displacement law. Explanation of Infrared Radiation:

 Infrared is one of the many invisible rays in sunlight, discovered by the British scientist William Herschel.1800Yearly discovered, also known as infrared thermal radiation,He used a prism to split sunlight and placed thermometers at various positions along the strips of different colors, attempting to measure the heating effect of each color of light. The result showed that the thermometer on the side of the red light heated up faster. Therefore, the conclusion was drawn...:On the outer side of red light in the solar spectrum, there must be invisible light, which is infrared. It can also be regarded as a medium for transmission. Infrared light on the solar spectrum has a longer wavelength than visible light.0.75~1000μmInfrared light can be divided into three parts: near-infrared, with a wavelength of0.75~1.50μmBetween;Mid-infrared, wavelength of1.50~6.0μmBetween;Far-infrared, wavelength of6.0~l000μm Between.
