The fabric inspection is indispensable for evaluating the quality of textiles. However it has been performed by the visual evaluation. The visual inspection is a burden to the operator, and it is also difficult to evaluate qualitatively and quantitatively. Automation and labor saving are desired to improve uniformity and quality. Therefore, in this paper we examined the possibility of the fabric inspection system, which is based on analyzing the autocorrelation function obtained from the
