The international system of units, which is at the basis of every accurate measurement, requires coherent definitions for its basic units (eg. metre, second, kelvin). Unfortunately, at the moment this is not so, and a global call has gone out to redefine every basic unit in terms of fundamental constants, which are by definition the same anywhere and anytime. This project will develop a new laser-based approach to measuring temperature which can be widely deployed and uses fundamental principles for its operation: this can bring accuracy to thermometry in industry for the first time. These outcomes will generate high-level recognition for this Australian project and provide opportunities for high level research training.

国际单位制是每一种精确测量的基础，需要对其基本单位（例如：米、秒、开尔文）。 不幸的是，目前情况并非如此，一个全球性的呼吁已经发出，要用基本常数来重新定义每一个基本单位，根据定义，这些基本常数在任何地方和任何时候都是相同的。该项目将开发一种新的基于激光的温度测量方法，该方法可以广泛部署，并使用其操作的基本原理：这可以首次为工业测温带来准确性。 这些成果将为这个澳大利亚项目带来高水平的认可，并为高水平的研究培训提供机会。
