Mueller Matrix Imaging Ellipsometry for Nanostructure Metrology

Optics Express, 2015
In order to achieve effective process control, fast, inexpensive, nondestructive and reliable nanometer scale feature measurements are extremely useful in high-volume nanomanufacturing. Among the possible techniques, optical scatterometry is relatively ideal due to its high throughput, low cost, and minimal sample damage.

Mueller matrix by imaging polarimeter

SPIE Proceedings, 2012
Most of imaging polarimeters in the field measure only a few components of the Mueller matrix or their combinations such as Stokes vector, degree of linear polarization (DOLP) and degree of circular polarization (DOCP). Our imaging polarimeter was similar in that it produced two combinations of 16 Mueller components.

Digital Holographic Three-Dimensional Mueller Matrix Imaging

Applied Optics, 2015
A digital holographic Mueller matrix imaging method is proposed. A Mueller matrix is obtained from Stokes vectors that are calculated from the complex amplitude of the two orthogonal polarized lights. The complex amplitude is obtained by digital holography.

Mueller matrix imaging polarimeter at the wavelength of 265  nm

Applied Optics, 2023
Mueller matrix imaging polarimeters (MMIPs) have been developed in the wavelength region of >400nm with great potential in many fields yet leaving a void of instrumentation and application in the ultraviolet (UV) region. For the first time to our knowledge, an UV-MMIP is developed for high resolution, sensitivity, and accuracy at the wavelength of ...

Mueller matrix imaging for cancer detection

Proceedings of the 25th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (IEEE Cat. No.03CH37439), 2004
The Mueller matrix completely describes the optical polarization properties of a material. These properties are known to change with size of scatterers, birefringence, and number of scatterers. In cancerous and normal cells and tissues all of the above properties can change and therefore this approach can potentially be used to distinguish between non ...

Snapshot imaging Mueller matrix instrument

SPIE Proceedings, 2013
A novel way to measure the Mueller matrix image enables a sample's diattenuation, retardance, and depolarization to be measured within a single camera integration period. Since the Mueller matrix components are modulated onto coincident carrier frequencies, the described technique provides unique solutions to image registration problems for moving ...

Virtues of Mueller matrix imaging for underwater target detection

Applied Optics, 1999
We present a theoretical analysis on use of polarized light in the detection of a model target in a scattering and absorbing medium similar to seawater. Monte Carlo numerical simulations are used in the calculation of the effective Mueller matrix which describes the scattering process. A target in the shape of a disk is divided into three regions, each

Mueller matrix imaging polarimetry

Optical Engineering, 1995
The design and operation of a Mueller matrix imaging polarimeter is presented. The instrument is configurable to make a wide variety of polarimetric measurements of optical systems and samples. In one configuration, it measures the polarization properties of a set of ray paths through a sample.
