Fluorescent microthermography FMT is a microscopy technique for infrared imaging of temperature distribution in small scale the achievable spatial resolution is half micrometer and temperature resolution of 0.005 kelvin K . Time dependent measurements are possible, as the fluorescence lifetime is only about 200 microseconds. A thin film of a phosphor , europium thenoyl trifluoroacetonate , is applied on the surface e.g. an integrated circuit die integrated circuit die and illuminated by ultraviolet light at 340 380 nm, stimulating fluorescence at mainly 612 nm line. The quantum efficiency of fluorescence decreases exponentially with temperature, differences in emitted light intensity can be therefore used to assess differences on surface temperature, with hot areas showing as darker. ref http books.google.com books?id OX2cHKJWCKgC&pg PA713&dq semiconductor failure microphotograph&lr &as drrb is q&as minm is 0&as miny is &as maxm is 0&as maxy is &num 50&as brr 3&cd 3 v onepage&q &f false ref References reflist tech stub Category Infrared imaging Category Microscopy Category Thermometers Category Measurement ... more details
Orphan date February 2009 Overdriving a fluorescentlamp is a method of getting more light from each tube than is obtained under rated conditions. ODNO Overdriven Normal Output fluorescent tubes are generally used when there isn t enough room to put in more bulbs to increase the light. The method is effective, but generates some additional issues. This technique has become popular among aquatic gardeners as a cost effective way to add more light to their aquariums. While power compact fluorescent lights cost upwards of 60 100 in the US, a twin bulb overdriven lamp can be set up for 30. Overdriving is done by rewiring lamp fixtures to increase lamp current however, lamp life is reduced, and modifications of factory lamp wiring void all safety approvals such as Underwriters Laboratories UL or Canadian Standards Association CSA .
