  • Publication number: 20200333139
    Abstract: A gyroscope of the present invention includes a moving standing light wave generator to generate three moving standing light waves, an atomic beam source to continuously generate an atomic beam in which individual atoms are in the same state, an interference device that exerts a Sagnac effect through interaction between the atomic beam and the three moving standing light waves and a monitor to detect angular velocity or acceleration by monitoring an atomic beam from the interference device. The atoms are alkaline earth metal atoms, alkaline earth-like metal atoms, stable isotopes of alkaline earth metal atoms or stable isotopes of alkaline earth-like metal atoms.

  • Publication number: 20200300630
    Abstract: The present invention reduces measurement time. A gyroscope of the present invention includes a planar ion trap part, a microwave irradiation part, a laser irradiation part and a measurement part. The planar ion trap part includes two rf electrodes and two DC electrode rows, and forms ion traps that trap one ion on a substrate, a normal direction of the surface of the planar ion trap part corresponds to a z direction. The rf electrodes are disposed in the x direction on the substrate at a predetermined interval. The DC electrode rows are disposed in the x direction on the substrate so as to sandwich the two rf electrodes. The DC electrode rows each include at least five DC electrodes in the x direction. The trapped ions are spaced so as not to interfere with each other. The microwave irradiation part irradiates the ions with ?/2 microwave pulses.

  • Publication number: 20200256677
    Abstract: A gyroscope includes an atomic beam source to generate an atomic beam in which individual atoms are in the same state, a moving standing light wave generator to generate M moving standing light waves, an interference device to obtain an atomic beam resulting from the interaction between the atomic beam and the M moving standing light waves, a monitor to detect angular velocity by monitoring the atomic beam from the interference device and an accelerometer. The accelerometer acquires information on acceleration applied to the gyroscope and the moving standing light wave generator adjusts the drift velocity of at least M?1 moving standing light waves among the M moving standing light waves in response to the acceleration information.
