Free-Space Remote Sensing of Rotation at the Photon-Counting Level
Free-Space Remote Sensing of Rotation at the Photon-Counting Level is a scholarly work, published in 2018 in ''Physical Review Applied''. The main subjects of the publication include adaptive optics, digital image correlation, and optical tweezers. The authors have established\na 120-meter long free-space link between the rooftops of two buildings and show\nthat both the rotation speed and the rotational symmetry of objects can be\nidentified from the detected rotational Doppler frequency shift signal at\nphoton count level.
