The application discloses a kind of high-frequency single-photon tilt wavefront detection method and device, comprising the following steps: using wavefront modulation technique, high-speed coding and modulation are carried out to incident light wavefront;Single-photon signal acquisition, using single-photon detector, the single-photon signal focused after being focused by light signal guiding focusing device is collected, and the received photon signal is converted into electrical signal and is output by detector;Single-photon signal processing, single-photon signal wavefront reconstruction, according to the extracted wavefront tilt information, wavefront is reconstructed using wavefront reconstruction algorithm;Data correction;Data result analysis.The application uses wavefront modulation technique to carry out high-speed coding and modulation to incident light wavefront, can improve the performance of light signal guiding focusing device, enhance system flexibility, wavefront modulation technique allows the amplitude, phase, polarization state and wave vector direction parameter of light wave to be independently or simultaneously regulated, which greatly enhances the flexibility and functionality of light signal guiding focusing device, and can optimize imaging quality.

The invention discloses a grain surface flatness active monitoring system for a leveling robot, and relates to the technical field of leveling robots and grain surface leveling. The system comprises a plurality of base stations and a leveling robot which are arranged in a granary, the system further comprises a radio frequency module and a vibration sensing module, and the leveling robot comprises a robot body, a processing unit, a posture sensing module, a flash memory module, a scraper folding and unfolding module, a driving module and a communication module. A sensor in the leveling robot can automatically sense the self inclination angle and judge whether the grain surface is flat or not, the grain surface change is judged according to the change of the self inclination angle of the robot walking on the grain surface, the leveling robot does not have a blind area through data obtained through movement, and through mutual cooperation of a posture sensing module and a vibration sensing module, the grain surface can be leveled. And the grain pile distribution condition and the grain surface leveling condition are judged before and after the leveling module carries out leveling operation.
