英文摘要： Polarization, coherence, and spectrum are important properties of the light field. Researches around the characterization, regulation as well as the mechanism of interaction with random media have received more and more attention due to its novel applications in free space communication, super-resolution imaging, high-density data storage and optical micro-manipulation. Combined with the polarization, coherence and spectrum of the light field, this project will carry out theoretical and experimental study of the propagation properties of non-uniformly polarized polychromatic partially coherent radially polarized beam. We will explore applications in optical micro-manipulation and spectroscopic aspects. (1) It will investigate the properties of light field of polychromatic partially coherent radially polarized beam on propagation through optical systems and random media. We will focus on internal relations among the spectrum property, initial beam parameters as well as the random media, and develop rational approach to the regulation of the spectrum. (2) We will design various special correlated source beams and analyze the effects of different correlations on the polarization and spectrum after propagation, and find out new laws and novel methods regulating the beam parameters. (3) Experimental generation and measurement the beam parameters of polychromatic partially coherent radially polarized beam, and develop basic applications in optical manipulation and media spectroscopic. This project will enrich the theory and application basis of radially polarized beam and partially coherent spectrum.
