Infrared Technology

  1. 1. PRESENTED BY--- RAJIB MODAK DEPT- ECE SEM-6TH ROLL- 018
  2. 2. INFRARED RADIATION Is Electromagnetic Radiation With Longer Wavelength Than LIGHT.
  3. 3. INFRARED = INFRA + RED
  4. 4. The discovery of infrared radiation is ascribed to William Herschel, the astronomer, in the early 19th century. Herschel published his results in 1800 before the Royal Society of London.
  5. 5. Different regions in the infrared:: >> CIE division scheme >> Astronomy division scheme >> Sensor response division scheme >> Telecommunication bands in the infrared >> Thermal radiation scheme
  6. 6. The International Commission on Illumination (CIE) recommended the division of optical radiation into the following three bands: IR-A: 700 nm–1400 nm IR-B: 1400 nm–3000 nm IR-C: 3000 nm–1 mm
  7. 7. A commonly used sub-division schemes are:- * Near-infrared (NIR) * Short-wavelength infrared (SWIR) * Mid-wavelength infrared (MWIR) * Long-wavelength infrared (LWIR) * Far infrared (FIR)
  8. 8. CIE DIVISION CHART ::
  9. 9. BAND DESCRIPTOR WAVELENGTH O band Original 1260-1360 E band Extended 1360-1460 S band Short Wavelength 1460-1530 C band Conventional 1530-1565 L band Long wavelength 1565-1625 U band Ultralong 1625-1675 wavelength
  10. 10. Infrared (transmitting/passing) filters can be made from many different materials. One type is made of polysulfone plastic that blocks over 99% of the visible light spectrum from “white” light sources such as incandescent filament bulbs.
  11. 11. (A) Thermography : Infrared radiation can be used to remotely determine the temperature of objects. (B) Night vision : Infrared is used in night vision equipment when there is insufficient visible light to see.
  12. 12. (C) Other imaging : Cheaper digital cameras and camera phones have less effective filters and can "see" intense NIR, appearing as a bright purple-white colour. (D) Tracking : Infrared tracking, also known as infrared homing, refers to a passive missile guidance system.
  13. 13. * Heating * Communications * Spectroscopy * Meteorology * Astronomy * Art history * Biological systems * Health hazard
  14. 14. >> Moisture Detection >> Roof Leak Detection >> Mold Detection (Condition >>Energy Efficiency conducive for mold growth) >>Building Maintenance >> Water Leak Detection >>Machinery Maintenance >> Moisture behind Exterior >>Water Damage Restoration Finish Insulation System >> Loss Prevention
  15. 15. The Earth's surface and the clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to the atmosphere.
