Microrelief of the skin using a light transmission method

Archives of Dermatological Research, 2000
The recently developed Skin Visiometer, based on light transmission through blue-coloured silicone replicas, was used to study skin microrelief. Calibrated metal plates displaying lines with depths between 6 and 361 microns, were used to determine the accuracy, sensitivity and reproducibility of the technique as well as the parameters of importance ...

Longitudinal study of skin aging: from microrelief to wrinkles

Skin Research and Technology, 2011
Aim: To study the changes in skin microrelief and periocular wrinkles during the aging process.Methods: Replicas of the crow's feet area of volunteers were recorded in 1987 and 2008 and observed comparatively. Characteristic features were quantified by image analysis.Results: Observation shows that some microrelief features disappear and even merge ...

Diffraction by a microrelief grating

Journal of the Optical Society of America A, 2001
A model is proposed that describes diffraction by a microrelief grating. A microrelief grating is a grating of large period with grooves containing a periodic microrelief with a period considerably smaller than the period of the grating. In the model the interaction of the incident wave with the fine structure is taken into account rigorously while ...

ESTIMATION OF SOIL MICRORELIEF

Transactions of the ASAE, 1990
ABSTRACT Microrelief is an important soil surface feature that significantly affects wind erosion and, therefore, must be simulated for the new USDA-Agricultural Research Service Wind Erosion Research Model to adequately predict wind erosion. A new surface roughness index, the Cumulative Shelter Angle Distribution, which integrates oriented and non ...

An Automated Instrument for the Measurement of Bark Microrelief

IEEE Transactions on Instrumentation and Measurement, 2010
Bark microrelief is of importance to the physiological ecology of forested ecosystems because it has been documented to influence the distribution of corticolous lichens, stemflow generation, and forest biogeochemical cycles. Hitherto no instrument existed to characterize the inherent variability of bark microrelief with high spatial resolution.

Microrelief on ion-bombarded crystals and induced damage

Radiation Effects, 1970
Abstract Two types of bombardment experiments were performed. A first series on metallic spheres, examined by replicas, and a second series on thinned crystals, examined by transmission electron microscopy. The observations lead us to propose a model for the formation of the surface microrelief.

Skin microrelief profiles as a cutaneous aging index

Microscopy, 2016
An objective measurement of cutaneous topographical information is important for quantifying the degree of skin aging. Our aim was to improve methods for measuring microrelief patterns using a three-dimensional analysis based on silicone replicas and scanning electron microscope (SEM).
