Suppression of Speckle Noise in Digital Holography With Spatial and Temporal Domain Depolarization

IEEE Access, 2020
Speckle noise in digital holography has a great influence on image quality, and one of the reasons for the formation of speckle noise is that the degree of coherence for the reference light and the object light is too high and unnecessary noise is ...

Correlation between Lesion Progression and Depolarization Assessed by Polarization-Sensitive Optical Coherence Tomography

Applied Sciences, 2020
The detection of early stages of caries is still one of the major challenges in preservative dentistry. Since it is known from polarized light microscopy (PLM) that intrinsic enamel birefringence is affected by demineralization, polarization-sensitive ...

Extension and Limits of Depolarization-Fringe Contrast Roughness Method in Sub-Micron Domain

Sensors, 2021
To guarantee quality standards for the industry, surface properties, particularly those of roughness, must be considered in many areas of application. Today, several methods are available on the market, but some damage the surface to be tested as they ...

Is resistance to ischaemia of motor axons in diabetic subjects due to membrane depolarization? [PDF]

, 1990
The reasons for the resistance to ischaemia of peripheral nerves in diabetics are not well understood. We have now explored whether axonal depolarization underlies this phenomenon, as has previously been proposed.

Evaluation of the Relationship between T2*CMR and Cardiac Depolarization and Repolarization Parameters in Beta-Thalassemia Patients [PDF]

Journal of Kerman University of Medical Sciences
Background: Cardiac iron overload causes severe cardiac complications and is a leading cause of death in beta-thalassemia major patient. T2*CMR can detect preclinical cardiac iron overload.
