Transcript

  • 1. PRESENTED BY--- RAJIB MODAK DEPT- ECE SEM-6TH ROLL- 018
  • 2. INFRARED RADIATION Is Electromagnetic Radiation With Longer Wavelength Than LIGHT.
  • 3. INFRARED = INFRA + RED
  • 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. Different regions in the infrared:: >> CIE division scheme >> Astronomy division scheme >> Sensor response division scheme >> Telecommunication bands in the infrared >> Thermal radiation scheme
  • 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. 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. CIE DIVISION CHART ::
  • 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. 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. (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. (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. * Heating * Communications * Spectroscopy * Meteorology * Astronomy * Art history * Biological systems * Health hazard
  • 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. 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.
