Sensitivity of the Mueller matrix to the optical and microphysical properties of cirrus clouds
No full textAn adding-doubling method is employed to calculate the reflected Stokes
parameters for cirrus cloud layers composed of different habits and effective sizes. The
elements of the Mueller matrix are determined from the reflected Stokes parameters by
considering four different incident polarization states. The sensitivity of these elements is
observed by comparing different ice crystal habits, effective sizes, and optical depth. The
Mueller elements are strongly dependent on habit. The three habits, aggregate, bullet
rosette, and plate, are observed and the
M12/M11,M43/M11 and M44/M11 elements are discussed. The wavelength used is 0.532������m, which is the lidar wavelength used on
the CALIPSO satellite. The linear depolarization ratio is also discussed. The method of
subtracting the two depolarization ratios, is noted as another way to possibly better distinguish ice crystal habits.
The sensitivity of the Mueller matrix to effective size is also observed. For three
size distributions, the Mueller elements indicate no strong dependence. This may be due
to the assumption of randomly oriented ice. Also, using an absorbing wavelength might
provide dependence. Finally, the Mueller elements are dependent on optical depth. For a
greater optical depth, the strength of reflection increases while the polarization decreases.
As the optical depth increases, any peak-like features become non-existent
Polarization-sensitive Mueller-matrix optical coherence tomography
No full textMeasuring the Mueller matrix with optical coherence tomography (OCT) makes it possible to acquire the complete polarization properties of scattering media with three-dimensional spatial resolution. We first proved that the measured degree-of-polarization (DOP) of the backscattered light by OCT remains unity-a conclusion that validated the use of Jones calculus in OCT. A multi-channel Mueller-matrix OCT system was then built to measure the Jones-matrix, which can be transformed into a Mueller matrix, images of scattering biological tissues accurately with single depth scan. We showed that when diattenuation is negligible, the round-trip Jones matrix represents a linear retarder, which is the foundation of conventional PS-OCT, and can be calculated with a single incident polarization state although the one-way Jones matrix generally represents an elliptical retarder; otherwise, two incident polarization states are needed. We discovered the transpose symmetry in the roundtrip Jones matrix, which is critical for eliminating the arbitrary phase difference between the two measured Jones vectors corresponding to the two incident polarization states to yield the correct Jones matrix. We investigated the various contrast mechanisms provided by Mueller-matrix OCT. Our OCT system for the first time offers simultaneously comprehensive polarization contrast mechanisms including the amplitude of birefringence, the orientation of birefringence, and the diattenuation in addition to the polarization-independent intensity contrast, all of which can be extracted from the measured Jones or the equivalent Mueller matrix. The experimental results obtained from rat skin samples, show that Mueller OCT provides complementary structural and functional information on biological samples and reveal that polarization contrast is more sensitive to thermal degeneration of biological tissues than amplitude-based contrast. Finally, an optical-fiber-based multi-channel Mueller-matrix OCT was built and a new rigorous algorithm was developed to retrieve the calibrated polarization properties of a sample. For the first time to our knowledge, fiber-based polarization-sensitive OCT was dynamically calibrated to eliminate the polarization distortion caused by the single-mode optical fiber in the sample arm, thereby overcoming a key technical impediment to the application of optical fibers in this technology

Mueller matrix imaging for skin cancer detection
No full textOver one million Americans are afflicted with skin cancer each year. Even though skin cancer has a 95% cure rate, approximately 10,000 people die in the United States each year of this disease. The current ABCDE(F) detection method is not sensitive enough to detect skin cancer in its early stages and requires a biopsy for any suspicious lesions. A lot of unnecessary biopsies, which are painful and costly to the patient, are taken. Therefore, a noninvasive technique is needed that can accurately detect the presence of skin cancer. In this thesis, an optical approach will be presented that has potential to be a noninvasive skin cancer detection technique. Several morphological and biochemical changes occur as tissue becomes cancerous, and therefore the optical properties of the tissue can be used to detect skin cancer. A Mueller matrix imaging system has been developed by our group that measures the 16 or 36-element Mueller matrix, which completely describes the optical properties of the tissue sample. The system is automated and can collect the Mueller matrix in less than one minute. This system will be used to
image Sinclair swine, and data analysis techniques will be employed to determine if the system can distinguish between cancerous and noncancerous tissue. System software improvements will also be made, and a new calibration technique will be presented
