Using infrared light to measure the continuity of the enameled wire paint film, and discusses the problem of the matching sampling rate of the cross-correlation calculation window in the measurement. Under the premise of constant enameled wire speed, the infrared receiving tube located in the direction of movement of the enameled wire collects two reflected infrared light signals and performs crosscorrelation calculation after amplification processing. Then according to different sampling rates, select the appropriate cross-correlation calculation window. The relevant delay can be effectively ...
