奇点光学概论

Introductory Concepts of Singular Optics

奇点光学被认为是现代光学的一个新的分支学科,其研究对象已从完全相干光波场(相干奇点光学)推广到部分相干光波场(相关奇点光学),从单色光波场推广到多色光波场,从标量光波场推广到矢量光波场,从理论研究和计算模拟扩展到实验和应用.结合我们的工作,对奇点光学中一些基本概念和进展做了综合评述.奇点光学中取得的成果不仅有重要基础科学研究意义,而且有助于新奇点物理学的发展.

Singttlar optics has been recognized as a new branch of modern optics, and its research subject has been extended from fully coherent optical wavefields （coherent singular optics） to partially coherent wavefields （correlation singular optics）, from monochromatic optical wavefietds to polychromatic optical wavefields, and from scalar optical wavefields to vector optical wavefields, as well as from theoretical ：study and numerical simulation to experiments and applications. In this paper, based on our work, some basic concepts and recent advances in singular optics are reviewed. The results obtained in singnlar optics are of importance not only for the fundamental science, but also of benefit to developing novel singular physics.
