    • A mirror image suppression method adapted to an optical coherence tomography (OCT) system is provided. The mirror image suppression method includes the following steps: obtaining a tomography image of an object to be tested by using the OCT system; calculating one real image signal obtained from an nth specific-mode scan for a specific pixel of the tomography image based on image signals obtained from an (n−1)th and the nth specific-mode scans; obtaining one real image signal of each of a plurality of pixels in the tomography image based on the calculation in the step of calculating the one real image signal; and reconstructing the tomography image based on the real image signal of each of the pixels obtained in the step of obtaining the one real image signal to suppress mirror image signals of the tomography image.
    • 提供了适用于光学相干断层摄影(OCT)系统的镜像抑制方法。 镜像抑制方法包括以下步骤:通过使用OCT系统获得要测试对象的断层图像; 基于从第(n-1)和第n特定模式扫描获得的图像信号计算针对所述断层图像的特定像素的从第n特定模式扫描获得的一个实像信号; 基于计算一个真实图像信号的步骤中的计算,获取断层图像中的多个像素中的每一个的一个真实图像信号; 以及基于获得所述一个实际图像信号的步骤中获得的每个像素的实际图像信号来重建所述断层图像以抑制所述断层图像的镜像信号。

    • A handle mechanism is adapted to a projector having a case. The handle mechanism has a frame, a rod, a grip, a positioning element, and an elastic element. The frame is connected to the case and has a through hole. The rod penetrates through the through hole and is capable of moving relatively to the frame. The rod has a first end, a second end, an anchor portion at the first end thereof, a first positioning portion, and a second positioning portion. The grip is connected to the second end of the rod, wherein the anchor portions limit a movement range of the grip relative to the rods and the frame. The positioning element is located between the frame and the rod. The elastic element is located between the frame and the positioning element, and forces the positioning element to physically interfere with the first or the second positioning portion.
    • 手柄机构适用于具有外壳的投影仪。 手柄机构具有框架,杆,把手,定位元件和弹性元件。 框架连接到壳体并具有通孔。 杆穿过通孔并能够相对于框架移动。 杆具有第一端,第二端,在其第一端处的锚定部,第一定位部和第二定位部。 把手连接到杆的第二端,其中锚定部分限制把手相对于杆和框架的移动范围。 定位元件位于框架和杆之间。 所述弹性元件位于所述框架和所述定位元件之间,并且迫使所述定位元件与所述第一定位部件或所述第二定位部件物理地干涉。

    • A wall hanging apparatus for a projection apparatus comprises a fixing seat installed at the lower surface of the projection apparatus, supporting arm whose lower end is fixed on the surface of the fixing seat and reflection mirror fixed at the upper end of the supporting arm and corresponded to a projection lens of the projection apparatus. Whereby, the projection apparatus can have both the portability of a prone type projection apparatus and space saving characteristic of a ceiling hanging type projection apparatus and can be used in an indoor space with a lower height to allow the usage of the projection apparatus is diversified. And, a trapezoid deformation of an image caused from the deviation of the angle of incidence can be modified effectively and quickly by adjusting the angle of the reflection mirror.
    • 用于投影装置的挂墙装置包括安装在投影装置的下表面处的固定座,其下端固定在固定座的表面上的支撑臂和固定在支撑臂的上端的反射镜对应的支撑臂 投影装置的投影透镜。 由此,投影装置既可以具有倾斜型投影装置的便携性,也可以具有吊顶式投影装置的节省空间的特征,能够在具有较低高度的室内空间中使用,从而使投影装置的使用多样化。 并且,通过调整反射镜的角度可以有效地和快速地改变由入射角的偏差引起的图像的梯形变形。
