A quantum sensor for velocity
An innovative concept for improving the sensitivity of a quantum sensor for velocity measurement has made versatile applications in the aerospace industry possible. The new procedure allows high velocities to be recorded quickly with high accuracy and in a large dynamic range. For this purpose, a conventional Doppler measurement is complemented by an additional element of a rubidium cell, and the phase of the laser light is then analyzed. In this way, the resolution of velocity measurements used in conventional applications such as lidar or radar can be improved by several orders of magnitude. This new technology is currently being tested at laboratory scale and can easily be integrated into miniaturized modules. (Technology Offer 528)
