Arrangement and method for assessing tissue qualities

Device for analyzing qualities of a tissue, such as tissue thickness, tissue surface roughness and/or degree of tissue fiber linearization, comprising at least one light generating means (8,14, 15), a probe (1) with an extension (3), at least one fiber bundle (7,17) arranged in said extension (3), for conveying light from said light generating means (8,14, 15) to illuminate the surface of said tissue, and at least one light detecting means (5,20) characterized in that said light generating means (8, 14,15) generates light of known intensity, of at least one wavelength and including at least one polarization vector;

• that said extension (3) is designed for conveying light back-scattered from said tissue to said light detecting means (5,20), possibly including at least one fiber bundle (19);
• that said light detecting means (5,20) is designed for measuring the intensity and/or spatial distribution of light back-scattered from said tissue for at least one wavelength;
• that said intensity and/or spatial distribution detected by said light detecting means (5,20) is analyzed to derive qualities of said tissue, such as tissue thickness, tissue surface roughness and/or degree of tissue fiber linearization.
