    • An endoscope assembly with a main imaging device and a first light source is configured to provide a forward view of a body cavity, and further includes a detachable imaging device with an attachment member engageable with the distal end region of the endoscope, a linking member connected to the attachment member, and an imaging element with a second light source, wherein the detachable imaging device provides a retrograde view of the body cavity and the main imaging device. Light interference is reduced by using polarizing filters or by alternating the on/off state of the main imaging device, the first light source, the imaging element and the second light source so that the main imaging device and first light source are on when the imaging element and second light source are off and the main imaging device and first light source are off when the imaging element and second light source are on.
    • 具有主成像装置和第一光源的内窥镜组件被构造成提供体腔的前视图,并且还包括具有可与内窥镜的远端区域接合的附接构件的可拆卸成像装置,连接构件连接 以及具有第二光源的成像元件,其中所述可拆卸成像装置提供所述体腔和主成像装置的逆行视图。 通过使用偏振滤光器或通过交替主成像装置,第一光源,成像元件和第二光源的开/关状态来减小光的干涉,使得主成像装置和第一光源在成像 当成像元件和第二光源接通时,元件和第二光源关闭,主成像设备和第一光源关闭。
