Thermometer for Ultrasensitive Measurements: Temperature Control


Physics researchers at the University of Adelaide have successfully created a rare thermometer, efficiency of which is thrice the existing best thermometers so far. Reporting further, the experts expatiated that they were able to gauge temperature with the ‘nano-Kelvin thermometer’, through an accuracy of thirty billionths of a degree.

Researchers asserted that they have reached the highest level of precision in terms of measuring temperature at room temperature. Talking about the innovation, Professor Luiten one of the lead researcher said that temperature at subatomic level is not static rather fluctuating. This is the result of quantum level jiggling amongst the atoms. However, they were able to record this ‘jiggling’ at the real time with the help of their newly invented nano-Kelvin thermometer.

By utilizing light for measuring temperature, the thermometer exhibited the dynamic nanoworld, which is in ceaseless constant motion.

The thermometer into a crystalline disk, which corresponds to an exceedingly polished region, infuses two colors, red and green. Both the colors pass through the crystal but each with a different speed, which is contingent on the quartz’s temperature. For instance, higher the temperature, lesser will be the speed of red light relatively.

By compelling the two lights to move continuously, nearly one thousand times, around the rim of the crystal that is in shape of a disc, the device measures the infinitesimal difference in speed with an amazing accuracy.

Researchers envision that with this breakthrough, they would be able to gauge temperature near absolute zero conditions including ultrasensitive measurements. This invention looks promising after all, measuring temperature at quantum level would definitely enhance measurement precision and very deftly, it would revolutionize technologies employed in industrial and medical applications.
