Abstract

The invention provides a miniature nuclear magnetic resonance gyro air chamber. A miniature air chamber body in the nuclear magnetic resonance gyro air chamber is composed of lower encapsulation glass, an air chamber base plate, upper encapsulation glass and a working medium. A miniature reflector is composed of four miniature reflecting mirrors with the same appearance and size. According to the miniature nuclear magnetic resonance gyro air chamber, the miniature air chamber body in the millimeter scale or submillimeter scale can be obtained through a microprocessing method; detection light can be guided through the miniature reflector, a pump light source and a photoelectric detector in a nuclear magnetic resonance gyro can be arranged on the side of the air chamber, and thus the miniaturization of the whole instrument can be easily achieved. The miniature nuclear magnetic resonance gyro air chamber has the advantages that the size is small, the structure is compact, the problems of inner wall coating difficulty and film material selecting limitation are avoided, and the preparing method and process of the air chamber are simple.

Description

Technical field [0001] The invention belongs to the technical field of miniaturization of nuclear magnetic resonance gyroscopes, and particularly relates to a miniature nuclear magnetic resonance gyroscope gas chamber, which can be used as an atomic gas chamber of the nuclear magnetic resonance gyroscope. Background technique [0002] The nuclear magnetic resonance gyroscope is a solid-state gyroscope that uses the precession of the spin magnetic moment of the atomic nucleus to measure the angular velocity of inertial objects. The miniaturized nuclear magnetic resonance gyroscope is an important research direction of the new type of gyroscope. The nuclear magnetic resonance gas chamber is one of the core components of the nuclear magnetic resonance gyroscope, and its volume is one of the key factors restricting the miniaturization of the nuclear magnetic resonance gyroscope. Therefore, the preparation of micro-scale nuclear magnetic resonance gas cells is an important field in th...
