We study, theoretically and experimentally, the edge contrast performance when the illumination is provided by partially coherent fields originating from Gaussian or perfect optical vortex (POV) beams. We demonstrate that the latter permits one to better distinguish object discontinuities and improves the edge contrast. Our results suggest that active illumination procedures for target detection and discrimination could benefit from the additional flexibility provided by using partially coherent light from a POV.
期刊介绍:
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
