| 摘 要： | 针对商用空气折射率测量装置受到传感器采集性能和解算公式准确度的影响使得实际测量精度较低的问题,基于便携式多环境参数采集装置,设计了一套空气折射率测量系统,采集环境中的温湿度、大气压强状态信息,对3种折射率间接测量公式进行误差分析,并和商用环境补偿器进行性能对比。实验结果表明:在压强为100.17~100.21kPa,温度为21.1~21.9℃,湿度为45.9~58.0% RH的实验条件下,该测量系统的测量偏差比商用环境补偿器低2.69×10-7。 |

| Abstract: | Aiming at commercial air refractive index measuring device is affected by the acquisition performance of sensor and the accuracy of calculation formula, and its actual measurement accuracy is low. Based on portable multi-environmental parameter acquisition device, a set of air refractive index measurement system is designed to collect the information of temperature, humidity and atmospheric pressure in the environment. Error analysis of three indirect refractive index measurement formulas is carried out, and performance comparison with commercial environmental compensator is made. The experimental results show that under the experimental conditions of pressure 100.17~100.21kPa, temperature 21.1~21.9℃ and humidity 45.9~58.0% RH, the measurement error of the system is 2.69×10-7 lower than that of the commercial environmental compensator. |
