Abstract [en]

Based on the fourth-order correlation of light, lensless imaging with incoherent or partially coherent light is investigated theoretically by use of classical optical coherence theory. A novel lensless optical system for implementing imaging is proposed. The visibility and quality of the image are influenced by the coherence and transverse size of the light source. The results suggest useful imaging applications in x-ray, gamma-ray, or other wavelengths where no effective lens is available, and they have potential applications in optical metrology and holography.

Note

QC 20110708 Correction: "We want to point out that we missed three important but relevant papers on lensless imaging with thermal light. In Ref. [1], the authors first proposed the experimental protocol for lensless imaging with thermal light. In parallel, the authors of Refs. [2,3] proposed the same experimental protocol for lensless imaging with thermal light and they observed the lensless imaging with thermal light in experiment. In our previous Letter [4], by starting from the classical optical coherence theory (a different perspective from Refs. [1–3]), we achieved the same experimental method proposed in Refs. [1–3], and we mainly discussed the influence of partially coherent light on lensless imaging. Anyway, we are sorry for missing the above three papers. References 1. D. Cao, J. Xiong, and K.
