Gyroscopes Based On Nitrogen-vacancy Centers In Diamond

Gyroscopes have undergone a great development and achieved a widespread use in aerospace, robots,cameras and other fields in consumer electronics. Requirement of accuracy could be obtained by existing technology,but the desire of miniaturization still exist in all the levels.so miniaturization is one of development tendency in gyro-scopes. NV gyroscopes, with the characteristics of small size, are insensitive to the low frequency noise(fluctuation of magnetic field and temperature) under the help of pulse technology in magnetic resonance and attracts more and more interest of people. Two papers about NV gyroscopes have been published,they can be called eNVG and nNVG for shorteNVG have a requirement of stability of magnetic field, and initialization of nNVG is far from optimism, it needs a hard driving filed to polarize the nuclear spins of nitrogen.Here we proposed a scheme based on Aharonov-Anandan geometric phase in NV centers. We can extract the information of the rotation by observe observing the A-A phase in NV centers. For the adoption of dynamic decoupling. The gyroscope could suppress the low frequency noise.The requirement of stability of magnetic field and demand of strong driving field could not exist in this scheme. With the feature of wide-range, when sensitivity is 0.2 deg/s/(?)Hz,the range could be reach±6.69×106 deg/s with microsecond’magnitude of start-up time.This thesis contain three parts.In chapter l,we introduce three kinds of common gy-roscopes and the current situation of NV gyroscopes.In chapter 2,we propose a scheme of gyroscope based on Aharonov-Anandan phase in diamond and evaluate the perfor-mance index of this gyroscope.Some improved methods are also mentioned in this chap-ter. The chapter 3 is summary and scope.
