Abstract

Quantitative characterization of optical anisotropies is extremely important for wide fields and applications. The Mueller matrix, providing all the polarization-related properties of a medium, is a powerful tool for the comprehensive evaluation of optical anisotropies. Here, we propose a ptychographic Mueller matrix imaging (PMMI) technique, which features the Mueller matrix polarization modulation being introduced into the ptychography. The ptychographic reconstruction is performed for each polarization state, and the Mueller matrix can be determined from the reconstructed polarization-modulated amplitude images. A proof-of-concept of the proposed PMMI is implemented, and both simulations and experiments are conducted to demonstrate the validity of the method. Results indicate that the imaging resolution of the home-built PMMI apparatus achieves 1.550 µm at the wavelength of 633 nm, which is of the highest level for the Mueller matrix imaging to the best of our knowledge. A customized birefringent specimen is characterized, and both retardance and axis azimuth are quantitatively evaluated.

分层穆勒矩阵成像(PMMI):原理和概念验证演示。
光学各向异性的定量表征对于广泛的领域和应用极为重要。穆勒矩阵提供了介质的所有偏振相关特性,是全面评估光学各向异性的有力工具。在这里,我们提出了一种分层穆勒矩阵成像(PMMI)技术,其特点是在分层成像中引入穆勒矩阵偏振调制。针对每种偏振态进行分层成像重建,并从重建的偏振调制振幅图像中确定穆勒矩阵。对所提出的 PMMI 进行了概念验证,并通过模拟和实验证明了该方法的有效性。结果表明,自制的 PMMI 设备在 633 nm 波长下的成像分辨率达到了 1.550 µm,这是我们所知的穆勒矩阵成像的最高水平。对定制的双折射试样进行了表征,并对延迟和轴方位角进行了定量评估。
