    • The present invention provides an apparatus for white light observation and fluorescence diagnosis of skin diseases. More particularly, the present invention provides an apparatus for photodynamic diagnosis in which a plurality of excitation light emitting diodes (LEDs) is provided in an image pick-up head, the excitation LEDs being arranged to illuminate the entire examination region in the form of a mosaic by setting respective illumination light axes of the excitation LEDs to illuminate preassigned individual areas of the examination region, thus uniformly illuminating the examination region in a wide field of view with excitation light. In the apparatus for photodynamic diagnosis, the respective excitation LEDs are provided at the same or different angles based on the light axis of the object lens, and thereby it is possible that the beams of the light sources composed of the LEDs illuminate the field of view of the examination region uniformly, thus improving the uniformity of illumination. Moreover, the present invention provides an apparatus for photodynamic diagnosis in which warm white LEDs and cold white LEDs as white light sources are appropriately arranged so as to deliver natural colors and thereby to reproduce natural color images.
    • 本发明提供了一种用于白光观察和皮肤疾病荧光诊断的装置。 更具体地说,本发明提供了一种用于光动力学诊断的装置,其中多个激发发光二极管(LED)被提供在图像拾取头中,激发LED被布置成以整体形式照射整个检查区域 通过设置激发LED的各个照明光轴来照亮检查区域的预分配的各个区域,从而在激发光的宽视场内均匀地照射检查区域。 在光动力诊断装置中,基于物镜的光轴以相同或不同的角度设置各激发LED,由此,由LED组成的光源的光束可以照射视场 的检查区域均匀,从而提高了照明的均匀性。 此外,本发明提供了一种用于光动力诊断的装置,其中温白色LED和作为白光源的冷白光LED被适当地布置以便传送自然色,从而再现自然色图像。
