Abstract
The invention relates to a nuclear magnetic resonance gyroscope sensitivity detection unit and a manufacturing method of the nuclear magnetic resonance gyroscope sensitivity detection unit and belongs to the field of atom sensors. The nuclear magnetic resonance gyroscope sensitivity detection unit aims to solve the problems that an existing sensitivity detection unit is low in accuracy and can not meet the requirements of a nuclear magnetic resonance gyroscope. According to the nuclear magnetic resonance gyroscope sensitivity detection unit and the manufacturing method of the nuclear magnetic resonance gyroscope sensitivity detection unit, the main structure is completed by means of the 3D printing technology, and the positions of all elements are directly limited; lasers emitted by a VCSEL laser device are polarized through a polarizer, collimated through a small-focal-length collimation lens and then emitted into a nuclear magnetic resonance air chamber after the polarization state is adjusted through a 1 / 4 wave plate; alkali metal atoms and inert gas atoms in an atom air chamber are pumped into an excited state through pump light first, and then the emitted light of the nuclear magnetic resonance air chamber is emitted to the photosensitive surface of a photoelectric detector to complete detection of nuclear magnetic resonance signals. The nuclear magnetic resonance gyroscope sensitivity detection unit and the manufacturing method of the nuclear magnetic resonance gyroscope sensitivity detection unit are suitable for development of a micro-structure nuclear magnetic resonance gyroscope system.
Description
technical field [0001] The invention belongs to the field of atomic sensors. Background technique [0002] The nuclear magnetic resonance atomic gyroscope is a sensor that uses the atomic nuclear magnetic resonance frequency change to detect the angle change. The sensitive detection unit is the core component of the entire gyroscope. Its stability and accuracy determine the overall nuclear magnetic resonance atomic gyroscope of the system. Detection accuracy, however, the existing sensitive detection unit has low precision, high power consumption, and large volume, which cannot meet the requirements of nuclear magnetic resonance gyroscopes. Therefore, how to design a sensitive detection unit with high precision, low power consumption, and small size has become a manufacturing The key to an MRI gyroscope. Contents of the invention [0003] The present invention aims to solve the problem that the existing sensitive detection unit has low precision and cannot meet the requir...
