Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] like figure 1 A miniature uniaxial diamond gyroscope shown includes a gyroscope housing 11, an LED light source 1, a first plano-convex lens 2, a first annular permanent magnet 3, a first aperture 4, a diamond 5, a second aperture 6, The second annular permanent magnet 7, the second plano-convex lens 8, the filter plate 9, the photodetector 10, all devices are coaxially integrated inside the gyroscope housing;

[0022] The LED light source 1 is powered by the LED power supply interface 12 and can emit green light with a wavelength between 510nm and 550nm. One side of the plane of the first plano-convex lens 2 is adjacent to the LED light source 1 for converging the green light emitted by the LED light source 1 . The first annular permanent magnet 3 is installed close to the convex side of the first plano-convex lens 2, and the inner di...

Abstract

The invention relates to a tiny single-axis diamond gyro. A negative valence nitrogen-vacancy (NV<->) color center-embedded diamond material is sensitive to the angular velocity of a carrier, a low-power LED lamp replaces a laser device to provide polarization and detection lights, and the surface of diamond is coated with a microwave antenna to provide an NV-color center energy level control microwave and radiofrequency signal. The tiny single-axis diamond gyro has a simple and compact structure, can effectively improve the stability of a gyroscope and reduce the production cost, reduces the use cost of low-power devices, and has very large application potential in the field of inertial navigation and posture measurement systems needing gyroscopes with small size, low cost, low power and high stability.

Description

technical field [0001] The invention relates to the technical field of gyroscopes, in particular to a miniature single-axis diamond gyroscope, which can be applied to various navigation and attitude measurement systems that require gyroscopes with small volume, low cost, low power consumption and high stability. Background technique [0002] The gyroscope is a device used to measure the rotation information of the carrier, and it is an important sensor in the inertial navigation system. With the continuous advancement of micro-processing technology, a class of low-cost gyroscopes represented by MEMS gyroscopes have been widely used, but the long-term drift rate of MEMS gyroscopes is high. Therefore, a gyroscope with low cost, small size and high stability is urgently needed. [0003] Embedded NV - The diamond material of color center has the stability of solid material, and the sensitive element NV in unit volume - The concentration of color center is high, and microwave ...
