摘　　要：文中在光纤、电容液滴分析仪的基础上设计双光路光纤、电容液滴分析仪,增加鉴别液体的依据。通过对仪器中两路微弱光信号的分析研究,设计信号处理方案,并通过实验验证方案的可行性。An optical fiber-capacitive dorp analyzer （FCDA） which has double optical routes is presented in this paper. This instrument is based on the FCDA, and added the function of distiguishing more kinds of liquid. The two weak optical signals are analysed and a set of signal disposal method is designed. The test result verified the system.
