Textured surface analysis is essential for many applications. In this paper, we present a three-dimensional recovery approach for real textured surfaces based on photometric stereo. The aim is to be able to measure the textured surfaces with a high degree of accuracy. For this, we use a color digital sensor and principles of color photometric stereo. This method uses a single color image, inste...

BACKGROUND Breast implant-associated anaplastic large cell lymphoma (ALCL) is a distinctive type of T-cell lymphoma that arises around breast implants. Although rare, all cases with adequate history have involved a textured breast implant. The objective of this study was to determine the U.S. incidence and lifetime prevalence of breast implant-associated ALCL in women with textured breast impla...

Textured silicon nitride (Si3N4) has been intensively studied over the past 15 years because of its use for achieving its superthermal and mechanical properties. In this review we present the fundamental aspects of the processing and anisotropic properties of textured Si3N4, with emphasis on the anisotropic and abnormal grain growth of β-Si3N4, texture structure and texture analysis, processing...

Different optical characterization methods were applied to a series of microcrystalline silicon thin films, either as grown, textured, or subsequently polished, mirror-like. They reveal contributions of bulk and surface light scattering effects to the phenomenon of optical absorption enhancement. The enhanced light absorption in textured layers is mainly due to a longer optical path as a result...

The optics of axial silicon nanowire solar cells is investigated and compared to silicon thin-film solar cells with textured contact layers. The quantum efficiency and short circuit current density are calculated taking a device geometry into account, which can be fabricated by using standard semiconductor processing. The solar cells with textured absorber and textured contact layers provide a ...
