Making scientific measurements more accurate

Mike Tobar

Much of science relies on measuring; the more accurate the measurements, the more revealing the science.

Part of the research of this group involves developing precision measuring tools to test fundamental physics. Developing such measuring tools has commercial potential and the group is dedicated to commercialising their inventions and taking out patents in conjunction with industry.

Recently, Professors Ivanov and Tobar and PhD student Stephen Parker published research based on recycling power interferometers, very precise measuring instruments that improved the resolution of phase detection (that is, how waves travel in relation to each other).

In another paper, a high-power recycling interferometer was able to resolve the phase of a microwave signal more accurately than any other device, including current laser interferometers. The new device has the potential to greatly improve current tests involving relativity theory and the constancy of the speed of light.
