复杂的病毒很容易发生突变,在测试过程中为了保持一定的环境温度、湿度、气氛以及对于毒性强的病毒,为了确保工作人员的健康和安全,防止交叉感染,采用光纤传感技术是很有意义的。为了达到隔离遥测的目的,本实验采用了非功能型光强调制式光纤传感装置。 光散射法检测病毒是以病毒的理化性质为依据的。光波通过病毒悬浮液介质时,当病毒微粒大小约为入射光波的λ/10～λ/20时,发生瑞利散射,散射光强为 Complex viruses are prone to mutation. In order to maintain a certain degree of ambient temperature, humidity and atmosphere as well as to highly virulent virus, it is very important to use optical fiber sensing technology to ensure the health and safety of staff and prevent cross-infection during the testing meaningful. In order to achieve the purpose of isolation telemetry, this experiment used a non-functional light intensity modulation optical fiber sensing device. The light scattering method to detect the virus is based on the physical and chemical properties of the virus. Light waves through the virus suspension medium, when the virus particle size is about λ / 10 ~ λ / 20 of the incident light wave occurs Rayleigh scattering, scattering light intensity
