    • An endoscope for image pickup of an object by receiving image light with an image sensor includes an elongated tube. A fiber optic image guide includes a plurality of optical fibers being bundled, and has a distal tip, is inserted through the elongated tube, for transmitting the image light focused on the distal tip by an objective lens system in a proximal direction. A piezoelectric actuator is disposed on an outer side of the fiber optic image guide, for periodically displacing the distal tip, wherein the image sensor picks up the image light from the fiber optic image guide for plural times in synchronism with displacement, to form one synthesized image. A hood device is mounted on a head assembly of the elongated tube, and shiftable between a closed position for covering a distal end face of the head assembly and an open position for revealing the distal end face.
    • 通过用图像传感器接收图像光来对物体进行图像拾取的内窥镜包括细长管。 光纤图像引导件包括捆扎的多个光纤,并且具有远端,通过细长管插入,用于通过物镜系统沿近端方向透射聚焦在远端上的图像光。 压电致动器设置在光纤图像引导件的外侧上,用于周期性地移动远侧末端,其中图像传感器从位移与光纤图像引导件同步地拾取图像光以形成一个合成的 图片。 罩装置安装在细长管的头部组件上,并可在用于覆盖头部组件的远端面的关闭位置和用于露出远端面的打开位置之间移动。
