基于相干检测技术的LAPS味觉测试信号研究
Research on LAPS taste test signal based on coherent detection technology
摘要
Abstract
As light addressable potentiometric sensor photocurrent signal is weak and easily drowned by the noise,The DDS circuit provides the reference signal,a test system based on coherent detection technology is presented.The system can improve the signal-to-noise ratio and detect the LAPS taste test signal.The experimental results show that data collected by the system is highly consistent with data collected by the standard instruments,the scheme is feasible.关键词
