    • A device and method for reading and decoding paper or non- paper documents (12) including micro-perforated or "watermark" patterns and graphic patterns. The device comprises at least one image sensor (11) having light flashing means (33, 44) arranged to flash first light signals on a first side (12a, 12b) of a document (12), and image sensor reading means (31, 41) arranged to read the first light signals reflected by the graphic patterns (6, 7). The device further comprises at least one array of infrared light emitting means (14, 24) located in front of said image sensor (11) and arranged to flash second light signals on a second side (12b) of the document (12) whereby the image sensor reading means (31, 41) are arranged to read the infrared light signals passing through the micro- perforated or "watermark" patterns (5).
    • 一种用于读取和解码纸或非纸张文档(12)的装置和方法,包括微孔或“水印”图案和图形图案。 该装置包括至少一个图像传感器(11),其具有布置成在原稿(12)的第一侧(12a,12b)上闪光第一光信号的闪光装置(33,44),以及图像传感器读取装置 41)被布置成读取由图形(6,7)反射的第一光信号。 该装置还包括位于所述图像传感器(11)的前方的红外光发射装置(14,24)的至少一个阵列,并被布置成在文件(12)的第二侧(12b)上闪烁第二光信号,由此 图像传感器读取装置(31,41)被布置成读取通过微穿孔或“水印”图案(5)的红外光信号。
