Dermatologists who perform psoriasis UV phototherapy need a flexible tool that will optimize the UV radiation dose and automatically protect healthy parts of a patient s body from excessive UV radiation. To meet this need, Physical Optics Corporation (POC) proposes a UV light shaping technique with light delivered through fiber optics. By utilizing POC s proprietary electronically tunable light shaping diffuser (ETLSD) and fiber optics, this technique will permit a physician to adjust the size and shape of a light spot to correspond to the shape and size of a given skin lesion. It will also increase light uniformity and intensity, thereby avoiding the necessity for shielding material. POC s proposed techniques will constitute an inexpensive attachment to existing UV light sources, and will increase therapeutic efficiency and reduce side effects. PROPOSED COMMERCIAL APPLICATION The low cost components of the proposed technique will make if marketable as an attachment to home UV phototherapy units. It can be used in numerous medical illumination systems, combined with endoscopes, and in dental practices.

进行银屑病紫外线光疗的皮肤科医生需要一种灵活的工具，可以优化紫外线辐射剂量，并自动保护患者身体的健康部位免受过多的紫外线辐射。为了满足这一需求，物理光学公司（POC）提出了一种通过光纤传输光的UV光整形技术。通过利用POC专有的电子可调谐光整形扩散器（ETLSD）和光纤，该技术将允许医生调整光斑的大小和形状，以对应于给定皮肤病变的形状和大小。它还将增加光的均匀性和强度，从而避免屏蔽材料的必要性。POC提出的技术将构成对现有紫外线光源的廉价附着，并将提高治疗效率并减少副作用。提议的商业应用提议的技术的低成本组件将使其作为家庭紫外线光疗装置的附件销售。它可以用于许多医疗照明系统，结合内窥镜，并在牙科实践。
