Abstract

In this letter, we propose to study and visualize targets in sea-surface environments using polarimetric observables. To do so, we simulated a sea-surface condition to obtain corresponding results. In particular, a photon-tracking theoretical model is developed to represent the interaction between photons and targets in complex marine environments (changing number density and size distribution of water droplets and bubbles). Moreover, with the assistance of Monte Carlo algorithm, the developed photon-tracking model is able to illustrate the polarimetric characteristics in the detectors with high accuracy. To comprehensively analyze the obtained polarimetric characteristics of depolarizing samples changing with the marine environment, the different polarimetric observables are employed to characterize the depolarizing samples from a variety of perspectives, as well as the corresponding images by different polarimetric observables are illustrated. The relevant results demonstrate the proposed method can analyze the physical characteristics and provide a significant way to ocean target detection.

在海面环境中极化观测显示去极化目标

在这封信中，我们建议使用偏振观测来研究和可视化海面环境中的目标。为此，我们模拟了一个海面条件，以得到相应的结果。特别地，建立了一个光子跟踪理论模型来描述复杂海洋环境中光子与目标之间的相互作用（水滴和气泡的数量密度和大小分布的变化）。此外，在蒙特卡罗算法的辅助下，所建立的光子跟踪模型能够高精度地描述探测器的偏振特性。为了综合分析得到的去极化样品的极化特征随海洋环境的变化而变化，利用不同的极化观测资料从多个角度对去极化样品进行表征，并给出了不同极化观测资料对应的图像。实验结果表明，该方法能够较好地分析海洋目标的物理特性，为海洋目标检测提供了一种重要的方法。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
