摘要
所研制的实时指纹取像系统利用传统的光学全反射原理和激光全息光栅反射技术相结合的研究方法 ,解决了传统光学全反射指纹取像系统所存在的问题。给出了新型光学指纹取像系统的研究方法和光学设计的光路图。所研制的实时指纹取像系统图像具有无畸变、无失真。
A new method that uses a holographic grating and a prism to getting real-time image of fingerprint is put forward to solve the disadvantage of tradition way that gets image of fingerprint using a prism.In this paper,the design of a new system getting image of fingerprint is described.Using this system,the quality of fingerprint is so good that the pores on the ridges can be seen clearly.
