Contact image sensor, light guide module and manufacturing method thereof

The invention provides a light guide module. The light guide module comprises two end surfaces, an axis and a central part, the axis is orthogonal to at least one of the two end faces, the central part is arranged between the two end faces, the optical array is arranged in the central part, the optical array is arranged in a light path of a light beam output by the linear light source, and a specific angle which is not zero is formed between the optical array and the axis. Wherein the linear light source is arranged on one of the two end faces, and after the light beams pass through the optical array, the light beams output sensing light with uniform intensity in the radial direction of the axis. The invention further comprises a contact image sensor and a manufacturing method of the light guide module. 本发明提供一种导光模组，包括二端面、轴线以及中央部。轴线与二个端面的至少一者呈正交，中央部介于二个端面之间，且中央部之内配置光学阵列，光学阵列位于线性光源输出的光束的光路径中，且光学阵列与轴线之间具有不为零的特定角度。其中，线性光源配置于二个端面的一者，且光束通过光学阵列之后，光束沿轴线的径向输出均匀强度的感测光。本发明更包括一种接触式影像感测器以及导光模组的制作方法。
