Background

The deviation correcting detection system detects whether the detected strip is deviated or not by detecting the deviation amount signal, and most of the deviation correcting detection system at present utilizes the detected strip to shield light or ultrasonic parts to detect the deviation correcting edge, but the sensor is mainly suitable for opaque or sound-proof coiled materials, and the sensor is mainly suitable for the photoelectric detection of the original single sensor because the light incident to the sensor is still changed even when the edge is not moved, and the initial single sensor photoelectric detection is completely unsuitable for the materials with the light transmittance or sound transmittance changing along with the tension of the coiled materials although the materials can be used for specific semitransparent or porous materials. Although CCD or CMOS digital image sensor can be used for detecting the entangled edge of variable material, it has high cost and relatively slow speed.
