  1. Far-infrared astronomy

    Unreferenced date July 2007 Far infrared astronomy is the branch of astronomy and astrophysics that deals with objects visible in far infrared radiation extending from 30 m towards submillimeter wavelengths around 450 m . In the far infrared, stars are not especially bright, but we can see emission from very cold matter 140 Kelvins or less that is not seen at shorter wavelengths. Huge, cold clouds of gas and dust in Milky Way our own galaxy , as well as in nearby galaxy galaxies , glow in far infrared light. This is due to thermal radiation of Interstellar Dust interstellar dust contained in molecular clouds . In some of these clouds, new stars are just beginning to form. Far infrared observations can detect these protostar s long before they turn on visibly by sensing the heat they radiate as they contract. The center of our galaxy also shines brightly in the far infrared These emissions ... and cause it to glow brightly in the infrared . The Bolocam Galactic Plane Survey BGPS Bolocam Galactic Plane Survey mapped the galaxy for the first time in the far infrared. Except for the plane of our own Milky Way galaxy , the brightest far infrared object in the sky is central region of a galaxy called Messier 82 . The nucleus of M82 radiates as much energy in the far infrared as all of the stars in our galaxy combined. This far infrared energy comes from dust heated by a source that is hidden from view.

  1. Thermal infrared spectroscopy

    Thermal infrared spectroscopy TIR spectroscopy is the subset of infrared spectroscopy that deals with radiation emitted in the infrared part of the electromagnetic spectrum . The emitted infrared radiation, though similar to blackbody radiation, is different in that the radiation is banded at characteristic vibrations in the material. The method measures the thermal infrared radiation emitted as opposed to being transmitted or reflected from a volume or surface. This method is commonly used to identify the composition of surface by analyzing its electromagnetic spectrum spectrum and comparing it to previously measured materials. It is particularly suited to airborne and spaceborne applications. Thermal infrared spectrometers Airborne TIMS a multispectral radiometer flown on C 130, ER 2, and the Stennis Learjet aircraft.

The prominent blooming or glow often seen in the highlights of infrared photographs is an artifact of HIE and not of infrared light itself. This is because although conventional photographic films have an Anti halation backing anti halation layer that absorbs scattered light, HIE lacks this backing. Kodak HIE must only be loaded and unloaded in total darkness. ref This is because HIE lacks anti halation layers and has a completely transparent base rather than being directly due to infrared sensitivity. Film usually has a slightly fogged base and anti halation layers coated on it in order to stop light bouncing around in the substrate once the image has been taken. Light can enter film through the tail protruding from a 35mm canister and without a fogged base it will be piped into the film and expose it. Without an anti halation layer any light entering the substrate through the emulsion will be reflected back and forth inside the film, becoming diffuse as it travels and causing halation.

A more luminous system, emitting more than 10 sup 12 sup Solar luminosity solar luminosities in the far infrared, is called ultraluminous infrared galaxy ULIRG . An even more luminous system, emitting more than 10 sup 13 sup solar luminosities in the far infrared, is called hyperluminous infrared galaxy HLIRG . Most LIRGs and ULIRGs emit at least 90 of their light in the infrared . Most LIRGs and all ULIRGs show signs of recent or continuing interactions and disruptions. Many are starburst galaxies , and some also contain an active galactic nucleus . On average, ULIRGs spawn about 100 new stars yearly, as compared to our own galaxy which spawns one new star a year. ULIRGs are implicated in a variety of interesting astrophysical phenomena including the formation of quasar s and elliptical galaxy elliptical galaxies . Local examples of ULIRGs are often used as analogs of Galaxy formation and evolution galaxy formation at high redshift.

  1. Nondispersive infrared sensor

    A nondispersive infrared sensor or NDIR sensor is a simple spectroscopic device often used as gas detector . File NDIR.JPG thumb right 250px NDIR Analyzer with one double tube for CO and another double tube for hydrocarbons Principle The main components are an infrared source lamp , a sample chamber or light tube, a wavelength sample chamber, and gas concentration is measured electro optically by its Absorption electromagnetic radiation absorption of a specific wavelength in the infrared IR . The IR light is directed through the sample chamber towards the detector. In parallel there is another chamber with an enclosed reference gas, typically nitrogen . The detector has an optical filter in front of it that eliminates all light except the wavelength that the selected gas molecules can absorb. Ideally other gas molecules do not absorb light at this wavelength, and do not affect the amount of light reaching the detector.to compensate for interfering components. For instance, carbon dioxide CO sub 2 sub and water molecule H sub 2 sub O often initiate cross sensitivity in the infrared spectrum. As many measurements in the IR area are cross sensitive to H sub 2 sub O it is difficult to analyse for instance sulfur dioxide SO sub 2 sub and nitrogen dioxide NO sub 2 sub in low concentrations using the infrared light principle.

There are also filters which are used in solid state electronics solid state Charge coupled device CCD or CMOS video cameras to block IR due to the high sensitivity of many camera Charge coupled device sensors to near infrared light.

    A infrared point sensor is a point gas detector based on the nondispersive infrared sensor technology. Principle Dual source and Passive infrared sensor dual receivers are used for self compensation of changes in alignment , light source intensity and component efficiency. The transmitted beams from two infrared sources are superimposed onto an internal beam splitter . 50 of the overlapping sample and reference signal is passed through the gas measuring path and reflected back onto the measuring detector. The presence of combustible gas will reduce the intensity of the sample beam and not the reference beam , with the difference between these two signals being proportional to the concentration of gas present in the measuring path. The other 50 of the overlapped signal passes through the beam splitter and onto the compensation detector . The compensation detector monitors the intensity of the two infrared sources and automatically compensates for any long term drift. Mean time between failures may go up to 15 years. Micro heaters Micro Heating element heaters can be used to raise the temperature from optical surfaces above ambient to enhance performance and to prevent condensation on the optical surfaces. Range Toxic gases are measured in the low parts per million Parts per notation ppm range. Flammable gases are measured in the 0 100 lower flammable limit LFL or lower explosive limit LEL range.
