Thermal imaging cameras

Horizon oil spill, as underwater explorer robots equipped with cameras were able to send images of the damaged oil well as well as reports on how repairs were proceeding. Thermal-imaging cameras can also identify regions on fire even as they allow rescue robots to seek out injured humans trapped in fires or under rubble. 

Recently I purchased a thermal imaging camera to help us find hotspots on pumps and other equipment that are about to fail. The picture here shows a photo taken by the camera and the hotspots on pumps which could potentially mean eventual component failure. 

The uneven heat baiance in the moid is often a reason for distorted parts. Using thermal imaging cameras, which are now affordable, hot spots in the mold, can be seen and valuable support for the optimization, not only for the warpage, is provided. The intensification of the temperature control, by pulsed cooling or sintered mold inserts, for example, often leads to significant cycle time reductions. 

In general, the sensitivity of the method is reduced as the depth of the defect from the surface monitored by the thermal imaging camera is increased. The sensitivity is best expressed... 

The detectors used for this focal plane array (FPA) are intended to be the same as are used for both the SIRTF FPA[1] 2tnd also for the Cincinnati Electronics 256 X 256 pixel infrared thermal imaging camera FPA. Thus, there is a considerable savings in cost and tedmology development realized, and consistent results can be obtsdned. 

Modern photovoltaic infrared cameras can detect heat in the form of IR radiation from objects. The picture obtained thereby provides a two-dimensional thermal image that is a spatial map of the temperature and emissivity distribution of all objects in the picture. The technique was used to test the activity of heterogeneous catalysts [40] and thereafter to detect enantioselective lipases on microtiter plates [30,31]- The method is useful for identifying highly enantioselective hits. However, because quantification has not yet been achieved, the assay cannot readily be used to detect small differences in enantioselectivity.
