摘要
电子轰击型有源像素传感器(Electron Bombarded Active Pixel Sensor,EBAPS)作为一种数字化微光成像器件,以其成像系统具有小型化、低成本和低功耗的优势,以及在昼夜条件下连续拍摄时具备清晰成像的能力,成为微光成像领域的研究热点。文章基于国产某型EBAPS微光器件,利用FPGA作为核心处理器,完成了EBAPS器件驱动电路、图像处理和跟踪电路、显示电路的设计。同时,构建了满足昼夜复用的光学系统,搭建了一种小型化的手持成像跟踪系统。实验结果表明,该EBAPS昼夜成像系统可在1×10^(-4)~1×10^(4) lx照度条件下实现良好的成像和跟踪效果。
As a digital low-light imaging device,the electron-bombarded active pixel sensor(EBAPS)has the ability to obtain a clear image under both day and night conditions.Compared with visible light and infrared imaging,its imaging system has the advantages of miniaturization,low cost,and low power consumption,making it a popular research topic in the field of imaging.Adopting a fully domestic EBAPS low-light device concept and FPGA as the main processor,an EBAPS device driving circuit,image processing and tracking circuit,and display circuit were completed.Using an optical system that satisfied the requirements of both day and night,a miniaturized handheld imaging and tracking system was built.The experimental results show that the EBAPS imaging system realizes clear imaging and good tracking effects under illuminance conditions ranging from 1×10^(-4) to 1×10^(4)lx.
