具备图像鉴伪功能的接触式图像传感器制造技术

本实用新型专利技术涉及接触式图像传感器，详细讲是一种带紫外线光源具有钞票或其他图像鉴伪功能装置的接触式图像传感器，其特征在于透镜上方或下方设有紫外光滤光膜，光电转换芯片上可以是对应紫外油墨标志局部也可以是全部设有红绿蓝或其他特定波长光透光膜，紫外光滤光膜可以把紫外光源发光经紫外油墨反射的紫外光过滤掉，并通过紫外光源发光经紫外油墨反射的红绿蓝等颜色光，使得反射到光电转换芯片上仅为反映紫外油墨反射特征的红绿蓝等颜色光，特定波长光透光膜，可以滤掉特定波长外的光而只通过特定波长的光，使光电转换芯片只接收反映紫外油墨反射光颜色更为具体特征的特定波长的光，从而实现通过配比反射特定颜色光的紫外油墨来提高假钞等的仿真难度。（*该技术在2018年保护过期，可自由使用*）

Contact type image sensor with image pseudo identification function

The utility model relates to a contact type image sensor, with is contact image sensor with a UV light source with money or other image false distinguishing function device, which is characterized in that the above or below the lens with UV filter film, photoelectric conversion chips can be of UV ink marks can also be provided with all the local red green blue or other specific wavelength light transparent film, UV filter film to UV light reflected by UV ink UV filter, and through ultraviolet light by UV reflective ink such as red green blue color light, only reflect UV ink reflection characteristics of red green and blue color light makes the reflection to the photoelectric conversion the chip, a specific wavelength of light film, can filter out specific wavelengths of light outside and only through the specific wavelength of light, the photoelectric conversion chip receives only reflect purple The external ink reflects the light of more specific characteristics of the specific wavelength, thereby achieving the difficulty of simulating counterfeit banknotes by matching the ultraviolet ink of a particular color light.
