摘要： A system (1) reads an information code (C) formed on a medium (10). The code has light modules and dark modules. The areas of the light modules are produced as inversion areas inverted light reflection characteristics. The areas of the dark module areas are produced as non-inversion areas non-inverting light reflection characteristics. A reader (40) emits illumination light of wavelengths including infrared light wavelengths to the code (10), and images the code (10) under the illumining light emission. The inversion areas, that is, the light module areas, can be dark under the visible light, but can be a light color due to its inverted light reflection characteristics. The light modules can thus be imaged by the reader (40) under the illumining light emission, providing distinguishable detection of the inversion and non-inversion areas, allowing the light and dark modules to be extracted for decoding.

摘要翻译： 系统（1）读取形成在介质（10）上的信息码（C）。 该代码具有灯模块和暗模块。 光模块的面积是反转区反转光反射特性。 暗模块区域的区域产生非反转区域的非反相光反射特性。 读取器（40）向码（10）发射包括红外光波长的波长的照明光，并且在发光的光发射下对代码（10）进行成像。 反转区域，即光模块区域，在可见光下可能是暗的，但由于其反射的光反射特性，可以是浅色。 因此，可以通过在发光的发光下的读取器（40）对光模块进行成像，从而提供反转和非反转区域的可区分的检测，从而允许提取亮和暗模块以进行解码。
