Abstract
An oscillation device, such as a frequency standard or 'atomic clock', is disclosed. The device comprises: a system capable of undergoing transitions between different energy states, the transitions defining at least a first resonance frequency and a second resonance frequency; an excitation device arranged to induce the system to undergo such transitions; a detection device arranged to detect a response of the system caused by the excitation device, to produce an output; and a controller arranged to receive the output, to control the excitation device to stimulate said transitions, and to obtain signals corresponding to at least the first and second resonance frequencies; wherein the controller is also arranged to process the obtained signals to produce a corrected output signal that is compensated against at least one influence on the resonance frequencies of the system.
