Abstract: A textile pattern processing system using a He-Ne Laser to scan a textile multi-coloured pattern is described. Owing to the diversity of the selected absorption of different colours to monochromatic light, the colour signals are first transformed into corresponding grey levels and then converted via optoelectronic device and A/D conveters into jacquard information represented with colours. The jacquard information processed by a minicomputer controls a jacquard card punch to produce jacquard cards for weaving. Eight selected colours can be recognized reliably. The sampling speed is 1000 pattern elements per second and the efficiencwy can be increased for 3 to 6 times more than that by the classic technque.
