Abstract

The invention relates to a diamond gyroscope with a color center, adopts a diamond material internally containing the high-concentration nitrogen-vacancy (NV-) color center as a sensitive element, realizes the control and the detection in the electronic energy level by using optical and microwave means and realizes the carrier angular velocity measurement. The diamond gyroscope with the color center has the advantages of room temperature operation, small volume, low cost and the like; compared with an existing gyroscope such as an MEMS (Micro Electro Mechanical System) and the like under same positioning, the diamond gyroscope with the color center is higher in theoretical sensitivity, and better in stability, has an important value on developing atomic spinning effect-based high-stability and small-volume solid-state atomic gyroscope, and is used for an inertial navigation and gesture measurement system in all fields in future, specially in the civil low-precision field.

Description
