“…Their experimental results show that the simulation results of the model using the parameters inverted by one fixed incident angle are in good agreement with the measurements of other fixed incident angles of the coating surfaces, which verifies the accuracy of the model. In 2021, Chen H. et al proposed a multi parameter pBRDF model that can better describe the infrared polarization scattering characteristics of coatings [19]. In 2022, Shen S. et al from the National University of Defense Technology proposed a method for calculating the degree of polarization of laser backscattering from a typical geometric rough surface at long distance based on the pBRDF model [20].…”

In order to analyze the performance of a light detection and ranging system based on polarization modulation, it is necessary to theoretically analyze and model the polarization scattering characteristics of common target materials. In this paper, the shortcomings of the classical Hyde pBRDF (polarization bidirectional reflectance distribution function) model are analyzed. Based on the research results of many researchers in recent years, a new six-parameter pBRDF model is proposed. To verify the accuracy of the proposed model, this paper builds a measurement system for the polarization scattering characteristics of the target surface in the laser active imaging scene, and the polarization scattering characteristics of two common materials, namely a white paint coating and an aluminum plate, are measured. Based on the measurement results of the DOP (degree of polarization) of the scattered light of the target material and the BBO-FA (biogeography-based optimization-Firefly algorithm) algorithm, we performed inversion calculations on the key parameters of the target material. Using the parameters of the target material obtained via inversion, we use the model to simulate the Stokes vectors of the target and compare the simulated values of Stokes vectors with the measured values to verify the accuracy of the model. The verification results show that the simulation results of Stokes vectors are in good agreement with the measurement results for these two materials, and the introduction of various improvements to the model can effectively improve the accuracy of the model, which provides a tool for studying the performance parameters of a laser three-dimensional imaging system based on polarization modulation.

This paper explores the application of the Mueller matrix and integral equation method in the study of depolarization on material surfaces. The depolarization phenomenon on material surfaces holds significant importance in target detection and optical applications. The Mueller matrix serves as an effective tool for characterizing the polarization properties of optical devices, while the integral equation method offers a numerical approach for calculating the distribution of optical fields. This study delves into the fundamental principles and theories of the Mueller matrix and integral equation method, providing a detailed account of their simulation and experimental applications in investigating material surface depolarization. The combination of experimental measurements and theoretical simulations allows for a more in-depth understanding of the mechanisms and influencing factors of surface depolarization, as well as its impact on detection and identification. The research findings indicate that the Mueller matrix and integral equation method provide robust tools for understanding and analyzing material surface depolarization, with significant implications for optimizing detector device performance. Future research may further expand the application domains of these methods and explore their integration with other techniques and approaches to achieve more accurate and comprehensive studies of material surface depolarization.
