基于反射式共聚焦显微镜的高速数据传输系统设计
Design of High-speed Data Transmission System Based on Reflective Confocal Microscope
摘要
Abstract
In order to meet the requirements of data transmission rate and imaging frame rate index in reflective confocal microscope,and with the scanning mode of galvanator,a Gigabit Ethernet high-speed transmission system based on FPGA(Field Programmable Gate Array)is designed.Confocal microscope scanning consists of vibration mirror two-dimensional image,due to the line scan time is not fixed,resulting in the image reconstruction each line data points will be slight deviation,the upper machine cannot be in one-dimensional data flow according to different line points reconstruction two-dimensional image.In this paper,an information insertion module based on UDP protocol is designed to insert the frame,row,package and row point information of the corresponding image in each UDP package.The upper computer can recon-struct the image of different row points according to the row point information in the UDP package.At the same time,the upper computer can also judge whether there is packet loss in the transmission process through frame,row and packet information,and process the missing row da-ta through the imaging algorithm,solving the common packet loss problem in UDP.The experimental results verify the reliability and effective-ness of the transmission system.After testing,the actual transmission bandwidth of Ethernet reaches 986 Mbps,and the frame rate can reach 42 fps,realizing the high-speed data transmission required by the reflective confocal microscopic imaging system.关键词
