The Rotational Doppler Effect of Twisted Photons in Scattered Fields (Laser Photonics Rev. 17(10)/2023).

This scheme opens a path for the application of scattered twisted photons during light detection. B The Rotational Doppler Effect of Twisted Photons in Scattered Fields b In article number 2201022, Jiamin Wu, Qionghai Dai, and colleagues study the Doppler frequency shift characteristics of scattered twisted photons induced by various rotating rough surfaces and exploit the SPSF method to extract RDE in scattered light with a generalized non-vortex simple source.
