Abstract
A digital signal processor system is provided which detects defect in tubular knit fabric. The signal processor system is attached to a circular knitting machine or the like and utilizes a fiber optic scanning head for obtaining light reflectance data from the material. Fiber optic material is utilized to project light against the fabric web and another fiber optic bundle is utilized to read reflected light. A opto-sensor pixel array is utilized to provide voltage data to a digital signal processor which then analyzes the data to determine the existence of end out, holes, light or heavy yarn and needle run conditions.
