dc.description.abstract Speckle patterns observed by reflected light from a multi-layered skin tissue are theoretically studied. Biological and optical factors related with volume concentration of melanin in epidermis and of blood in dermis, which affect the speckle image contrast, are discussed. Examples are given of speckle patterns formed outside tissue by light multiply scattered in tissue depth under laser irradiation at various wavelengths. en_US
dc.description.abstract Studiul teoretic a structurii-specl, care poate fi observată în lumina reflectată într-un țesut de piele multi-strat. Sunt discutați factorii biofizici și optici asociați cu concentrația volumică de sânge în derma și melanina epidermei, care influențează asupra contrastului imaginilor speclelor. Sunt prezentate exemple a structurelor-specl, formate de lumina împrăștiată în mod repetat în adîncimea țesuturilor, la iradierea cu fasciculul laser de diferite lungimi de undă. ro
dc.description.abstract Une étude théorique du speckle observé dans la lumière réfléchie à partir d'un tissu multi-couches de la peau. Les facteurs biophysiques et optiques évoqués liés à la concentration du volume sanguin dans le derme et l'épiderme de la mélanine, ce qui affecte le contraste de l'image de tavelures. Des exemples du speckle formée par la lumière de façon répétée dispersés dans le tissu en vrac par irradiation d'un faisceau laser à différentes longueurs d'onde. fr
dc.description.abstract Теоретически исследована спекл-структура, наблюдаемая в отраженном свете от многослойной ткани кожи. Обсуждены биофизические и оптические факторы, связанные с объемными концентрациями крови в дерме и меланина эпидермиса, которые влияют на контраст изображения спеклов. Приведены примеры спекл- труктуры, образованной светом, многократно рассеянным в толще ткани, при облучении лазерным пучком на различных длинах волн. ru
