Optical medical treatment device using polarization

Abstract

Polarized light-based phototherapy equipment according to the present invention is designed to focus light from a halogen lamp (1) using a light-focusing lens (6), and then to direct the focused light to a revolving plate (3) that is formed with a pair of cutouts (3a). The revolving plate (3) is rotated at 2,500 rpm. Accordingly, the focused light is significantly traveled through the revolving plate (3) at the cutouts (3a), but is predominantly blocked from passing through the revolving plate (3) in a range other than the cutouts (3a). As a result, the light is emitted to an optical fiber (7) in a pulse-like manner at a period of 0.012 seconds. A polarizing filter (8) at an end of the optical fiber (7) polarizes the pulse-like light. The polarized light is irradiated onto an affected area.
