The Factors and Improvement Measures for Accuracy of Correlation Velocity Measurement |
| |
| Abstract: | Correlation velocity measurement is built with sensitive field such as light,sound and so on.It is a measurement system that includes sensor,signal and display output,and has characteristics such as high accuracy and instant.The basic principle of the correlation velocity measurement is introduced,the influence factors for accuracy of the correlation velocity measurement are analyzed,the installation position of the sensor,the real-time simplification error and discrete sampling error are discussed,and the corresponding improvement measures are provided. |
