Abstract

The skin is the biggest human organ. It is also easily accessible and visible from the outside. Diagnosis of skin diseases such as melanoma skin cancer is often based on optical parameters, e.g. the widely known ABCDE rule of dermatoscopy. Not only cancer, but also inflammatory skin diseases are rated according to criteria which are at least partially based on optical criteria (see PASI- or EASI-scores) and often include subjective criteria. The standard instrument for an optical examination of the skin is the so-called dermatoscope. It is an epiluminescence microscope which nowadays often provides digital images of the suspected lesion. Due to the design as a contact-based device, most dermatoscopes face problems like suppression of perfusion, among others. That is why we developed a compact non-contact dermatoscope. To obtain further information about, for example, the tissue composition, an additional Mueller matrix (MM) measurement system was developed which can acquire the 4×4 MM spatially resolved for a 2D-image in a comparably short time.
