Detailed description of the invention
below in conjunction with accompanying drawing and case study on implementation, the invention will be further described:
a kind of dermoscopy as shown in the figure, comprise viewing system and illuminator, the rotation disc 5 that illuminator comprises at least one luminous body and can rotate around the optical axis of viewing system, rotation disc 5 offers at least one window 50, when rotation disc 5 carry out rotation switch time, the illumination light of luminous body is covered by rotation disc 5 or the illumination light of luminous body to be thrown light on dermoscopy work surface by window 50.Concrete enforcement structure is as follows:
dermoscopy comprises main basal base 10, and viewing system and illuminator are arranged on main basal base 10.Wherein: in main basal base 10, be provided with pedestal cylinder 11, one end of pedestal cylinder 11 is ocular end.
viewing system comprises sight glass 2, observes polaroid 4, observes polaroid 4 and can be fixedly installed on rotation disc 5, also can be arranged in viewing system between sight glass 2 and rotation disc 5, also can rotate around optical axis OOa.
the switching construction of the present embodiment is: rotation disc 5 is fixed on a rotating cylinder 12, rotating cylinder 12 offers bar shaped locating slot 52, main basal base 10 is provided with locating piece 100, and locating piece 100 can be fastened in locating slot 52 rotation of also sliding therein.Luminous body have employed LED illuminator 3, and LED illuminator 3 is for white or be with coloured.
illuminator comprises following several embodiment:
mode one:
the window 50 of rotation disc 5 arranges polarization of illumination sheet 51, and the illumination light of luminous body to be thrown light on dermoscopy work surface by polarization of illumination sheet 51, and photo polaroid 51 can only be arranged on a window 50, also can be arranged on multiple or all windows 50.
further scheme, as shown in Figure 3, polarization of illumination sheet 51 is distributed on multiple windows 50 of rotation disc 5, when rotation disc 5 rotates switching, can realize the switching of illumination path with/without polarization of illumination sheet 51.
mode two:
the front portion of luminous body arranges polarization of illumination sheet 51, and the illumination light of luminous body to be thrown light on dermoscopy work surface by polarization of illumination sheet 51 and window 50, and photo polaroid 51 only can be arranged on a luminous body front portion, also can be arranged on multiple or all luminous bodys anterior.
mode one and mode two need to be used in combination with observation polaroid 4 simultaneously.Namely the reflection high light of skin surface and veiling glare have been weakened because the polarization direction observing polaroid 4 and polarization of illumination sheet 51 intersects, and the rotation by observing polaroid 4 regulates the angle of polarization between itself and polarization of illumination sheet 51, to change the intensity of outgoing polarization light.
