The traditional atomic interference gravimeter, Mach?Zender type atomic gravimeter, has the problem of large volume, which affects the portability of the equipment. Peking University realizes the first compact atomic interference gravimeter based on the Bloch oscillation principle of moving optical lattice in China which is different from the conventional Mach?Zehnder atomic gravimeter. The sampling rate of the experimental system reaches 0.9 Hz, which can meet the needs of long?term real?time measurement，and the vertical displacement of atoms in the experimental system is about 3 cm. The sensitivity measured by the system reaches 4.6 × 10² μGal·Hz^-1/2. The resolution can reach 6.5(0.7) μGal in 2 800 s integration time. The experimental results point the future development direction for miniaturization and application of atomic interference gravimeter.
