Method for non-destructive testing of component, involves obtaining weights of averaged intensity values with correlation function to represent weighted average intensity values

摘要

The method involves measuring the predetermined number of intensity values per period for each pixel of camera. The current running index is obtained to generate the average intensity values for each pixel using specific formula. A brightness value is determined by summing the generated averaged intensity values. The running index is determined with the lowest brightness value. The running index of two correlation functions is moved, and the weights of averaged intensity values are obtained with the correlation function to represent the weighted average intensity values.
