Imaging Infrared

Shallow ordnance items such as mines can have a temperature gradient different from that of the surrounding soil. Infrared analysis can show the location of these items.

Miscellaneous. Chloroplatinic acid is used in the production of automobile catalysts. Platino-type prints based on reduction of Pt(II) to Pt(0) by a photosensitive reducing agent such as iron(III) oxalate are used in art photography (261,262). Infrared imaging devices based on a platinum siLicide detector have been developed (263). 

Unlike other infrared techniques, thermal or infrared imaging provides the means to scan the infrared emissions of complete machines, process or equipment in a very short time. Most of the imaging systems function much like a video camera. The user can view the thermal... 

Point-of-use infrared thermometers are commercially available and relatively inexpensive. The typical cost for this type of infrared instrument is less than 1,000. Infrared imaging systems will have a price range between 8,000 for a black and white scanner without storage capability to over 60,000 for a microprocessor-based, color imaging system. 

As an example of the importance of process parameters monitoring, consider a process pump that may be critical to plant operation. Vibration-based predictive maintenance will provide the mechanical condition of the pump and infrared imaging will provide the condition of the electric motor and bearings. Neither provides any indication of the operating efficiency of the pump. Therefore, the pump can be operating at less than 50 per cent efficiency and the predictive maintenance program would not detect the problem.

NIR (near-infrared) imaging has also been well introduced into polymer characterization, mainly because no laborious sample preparation is necessary. Spatial resolution approaches the range of mid-infrared imaging.

Optical methods are eminently suitable for imaging, the attractive property of photons being that they do not require vacuum. Hence, imaging under reaction conditions becomes possible. Among the successfully applied methods are infrared imaging (IRI) and reflection anisotropy microscopy (RAM) [72]. We will discuss ellipsomicroscopy for surface imaging (EMSI) in some detail here [74],...
