摘要:
A dermatoscope has a generally circular viewing opening, a plurality of light sources including first (551) and second groups (552) of light sources arranged about the viewing opening, a first polarizer (530) for polarizing light passing through the viewing opening, and a second polarizer (555) for polarizing light emitted from the first group of light sources, wherein the first and second groups of light sources are arranged at different distances from a center of the viewing opening so that light from the second group of light sources is not polarized by the second polarizer. A further dermatoscope has a head portion including a generally circular viewing opening, and at least one light source arranged proximate to the viewing opening and a body portion including an image capture device (155,165), wherein the head portion is pivotally attached to the body portion selectively allowing alignment of the center of the viewing opening with the center of the field of view of the image capture device. Yet a further dermatoscope has a generally circular viewing opening, a selectively extendable element that can be selectively extended coaxially with the viewing opening, and a contact element for contacting a surface to be viewed, the contact element being removably attachable to a distal end of the selectively extendable element.Linvention concerne un dermatoscope qui comporte une ouverture dobservation de manière générale circulaire, une pluralité de sources lumineuses comprenant un premier (551) et un second groupe (552) de sources lumineuses disposées autour de louverture dobservation, un premier polariseur (530) pour polariser la lumière passant à travers louverture dobservation et un second polariseur (555) pour polariser la lumière émise à partir du premier groupe de sources lumineuses, les premier et second groupes de sources lumineuses étant disposés à des distances différentes du centre de louverture dobservation, de sorte que la lumière provenant du second group
