Preliminary tests using a mirror as a standard sample show that the maximum Muller matrix element error of the colinear backscattering Muller matrix microscope can be reduced to a few percent.Zhenhua ChenYue YaoYuanhuan ZhuHui MaProceedings of SPIE...
When light scatters off an object, its polarization, in general, changes—a transformation described by the object’s Mueller matrix. Mueller matrix imaging is an important technique in science and technology to image the spatially varying polarization r
Generalized EllipsometryMeasuring a sample in reflection provides the necessary data (ψ and Δ) for calculating the refractive index and thickness of thin films. Because the AxoScan measures the full Mueller matrix, the measurement is not limited to isotropic films. Uniaxial and biaxial anisotropic fi...
The matrix size is 4x4 (When we consider only linear polarization, the size is 3x3). Polanalyzer provides basic Mueller matrix elements in numpy array. For example, the following code shows the Mueller matrix of a linear polarizer and a quarter-wave plate. import polanalyser as pa # Linear...
The first set includes planar slab and multilayer structures with specular reflection and/or transmission. The second set consists of grating structures with multiple propagation diffractions. Conclusion This study sheds light on the relationships between the Mueller matrix and the symmetries of structures...
Check out these videos showcasing our snapshot generalized ellipsometer (which measures eight elements of the normalized Mueller matrix). Additional details and explanations can be found in the video description. Companies interested in this technology are welcome to contact me for more information, as...
The system currently operates between 300 and 2700 nm, without the need to change any optical components except for the detector. Four lasers are employed as light sources (405, 532, 633, and 1570 nm) to test the performance in both reflection and transmission modes. Thus, the system is ...
Advances in the optical components and simulation software enable one to obtain most of the sixteen components of the Mueller Matrix for each wavelength of light instead of the typical Ψ and Δ. This is great importance when measuring highly anisotropic 3D scatterometry test structures. Finally, ...
Fig. 4 shows the normalized Mueller matrix elements from the 2×2 URB and LLB for a PECVD a-Si:H film measured in reflection at Conclusions A multichannel ellipsometer in the dual rotating-compensator configuration has been designed and constructed using optical elements fabricated from MgF2 to ...
