Short Wave Infrared Vs Near Infrared

Typical applications include medical and physiological diagnostics and research including blood sugar pulse oximetry functional neuroimaging sports medicine elite sports training.

Short wave infrared vs near infrared. Near infrared radiation or nir relates to the shorter wavelengths of radiation in the infrared spectrum. It converts into heat when it strikes an object. Performance improves by using the middle spatial resolution. Since silicon sensors have an upper limit of approximately 1 0μm swir imaging requires unique optical and electronic components capable of performing in the specific swir range.

Different fusion schemes exploiting the concept of hypersharpening. Long wave infrared energy is the heat radiated from an object which has received short wave infrared. Sensors unlimited inc part of utc. Eighty fresh rainbow trouts were divided into four batches which were separately preserved in ice for 1 3 5 and 7 days respectively.

Far infrared and near infrared waves are both part of this spectrum although they are very different from each other and can serve different purposes. One study for example classifies infrared light as anything above 760nm but some place the limit as high as 900 or 1000. Sensing in the shortwave infrared swir range wavelengths from 0 9 to 1 7 microns has only recently been made practical by the development of indium gallium arsenide ingaas sensors. Long wave vs short medium wave when we re talking about infrared heating we are describing the process of energy travelling in a straight line from the source which is then directed via optical reflectors.

Short wave infrared swir light is typically defined as light in the 0 9 1 7μm wavelength range but can also be classified from 0 7 2 5μm. Near infrared spectroscopy nirs is a spectroscopic method that uses the near infrared region of the electromagnetic spectrum from 780 nm to 2500 nm. Nir is used in the therapy called photobiomodulation or pbm. Short wave infrared energy comes directly from the sun but is not felt as heat.

Far infrared far infrared waves which are thermal waves are not visible to the eye and make up the heat we feel when we re near a fire or standing in the sunlight. We have just written an extensive article on photobiomodulation which you can find here.
