Single-shot polarization detection with a highly scattering system
Polarization detection plays a significant role in optics. However, the current detection methods usually involve mechanically rotating components, multiple measurement steps, complicated optical design, and precise microfabrication process. To address this issue, we propose a single-shot method to detect the polarization state of light based on a highly scattering system, which is constituted by a spatial light modulator and a highly scattering medium. When the incident light beam shaped by a superimposed wavefront is incident on a highly scattering medium, the foci represented the six components at horizontal, vertical, diagonal, antidiagonal, right circularly polarized, and left circularly polarized directions will appear behind the highly scattering medium simultaneously. By measuring the intensities of these six foci, all the Stokes parameters can be extracted. Taking advantage of the measured Stokes parameters, the orientation angle of major axis, the ellipticity, and the handedness of the polarization ellipse of incident light beam can be determined. Various light beams with different polarization states are detected to demonstrate the viability of the method. The experimental results and theoretical values are in a good agreement. Compared to the existing methods, this approach is fast, free of complicated fabrication, and independent of mechanical movement. The proposed method is expected to promote the development of real-time and broadband polarimetry.
期刊介绍:
Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology.
In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics.
APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field.
Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
