Researchers Develop New Method of Avoiding Noise Using Laser Light for Extreme Precision Measurements

Researchers at the Niels Bohr Institute at the University of Copenhagen have developed a new method to eliminate noise using laser light to take extreme precision measurements. The method, optomechanics, is a complicated interface between optical radiation and a mechanical movement.

The team created a new detector that does not need to be cooled down, unlike the traditional method that reduces the temperature of measurement equipment by 5 to 10 degrees Kelvin to reduce noise in the detector. This detector can operate at room temperature and hardly has any thermal noise except for the minimal fluctuations of the laser light, otherwise known as quantum noise.
