Rachel Godun from the United Kingdom’s National Physical Laboratory explained in a Physics viewpoint last year that researchers currently use satellites to compare measurements between different. Because of the much higher oscillatory frequency, nowadays optical clocks are outrunning the accuracy of cesium clocks by several orders of magnitude. Such electromagnetic oscillations are multi-THz, in contrast to the present standard cesium clocks that are based on a hyperfine transition at 9192631770 Hz. Since then, NIST researchers have focused on. The device operated at gigahertz frequencies, and the technology was promptly commercialized. The core components were about the size of a grain of rice. In 2004, NIST scientists created the first chip-scale atomic clock. An optical atomic clock employs a clock transition in the optical or visual regime, typically between 4 nm wavelength.
