    • A system for measuring a total track length of a telescopic lens includes a testing chart, a light source, a processor, a display screen and a range finder. The lens and an image sensor are received in a holder. The testing chart has a frame pattern and a plurality of line pair patterns. The testing chart faces and aligns with the image sensor for allowing the image sensor to capture an image of the testing chart. The processor analyzes the image generated by the image sensor, so as to obtain a modulation transfer function value representative of a precision focal position of the lens. The range finder measures a first distance between the image sensor and the range finder, a second distance between the lens and the range finder, and calculates a distance difference between the first and second distances to obtain the total track length of the lens.
    • 用于测量伸缩透镜的总轨道长度的系统包括测试图,光源,处理器,显示屏和测距仪。 透镜和图像传感器被接收在支架中。 测试图具有帧图案和多个线对图案。 测试图面向和与图像传感器对齐,以允许图像传感器捕获测试图的图像。 处理器分析由图像传感器产生的图像,以便获得代表透镜的精确焦点位置的调制传递函数值。 测距仪测量图像传感器和测距仪之间的第一距离,镜头和测距仪之间的第二距离,并计算第一和第二距离之间的距离差,以获得镜头的总轨道长度。

    • A backlight module includes a light guide plate and two light emitting elements for emitting light beams. The light guide plate includes first and second light guide portions and a connecting portion interconnecting the first and second light guide portions. The first light guide portion has two opposite first light incident surfaces at opposite sides thereof, and a first light output surface. The second light guide portion has a second light incident surface facing first light output surface of the first light guide portion. Each of the light emitting elements faces one of the first light incident surfaces of the first guide portion. The first guide portion receives the light beams via the first light incident surfaces and output them via the first light output surface. The second light guide portion receives the light beams from the first light output surface via the second light incident surface.
    • 背光模块包括导光板和用于发射光束的两个发光元件。 导光板包括第一和第二导光部分和互连第一和第二导光部分的连接部分。 第一导光部分在其相对侧具有两个相对的第一光入射表面和第一光输出表面。 第二导光部具有面对第一导光部的第一光输出面的第二光入射面。 每个发光元件面向第一引导部分的第一光入射表面之一。 第一引导部经由第一光入射面接收光束,经由第一光输出面输出。 第二导光部经由第二光入射面接收来自第一光输出面的光束。

    • An exemplary optical module (100) includes a lens barrel (20), a lens group (40), a spacer (60), and a filter (80). The lens barrel has an inner wall (201), and at least two securing grooves (206) formed on the inner wall. The lens group and the spacer are disposed in the lens barrel. The spacer includes an annular base (601) and a predetermined amount of projecting blocks (603) formed on a same side of the base (601). At least two first bending portions (604) are formed on the blocks bending toward a center of the base, and at least two second bending portions (606) are formed on the blocks bending outwards from a center of the base. The second bending portions are configured to be secured in the securing grooves of the lens barrel. The filter is secured on the spacer by the first bending portions.
    • 示例性光学模块(100)包括透镜镜筒(20),透镜组(40),间隔物(60)和过滤器(80)。 镜筒具有内壁(201)和形成在内壁上的至少两个固定槽(206)。 透镜组和间隔件设置在镜筒中。 间隔件包括环形基座(601)和形成在基座(601)的同一侧上的预定量的突出块(603)。 在朝向基座的中心弯曲的块上形成至少两个第一弯曲部(604),并且在从基部的中心向外弯曲的块上形成至少两个第二弯曲部(606)。 第二弯曲部分构造成固定在镜筒的固定槽中。 过滤器通过第一弯曲部分固定在间隔件上。
