Study on optical system of laser-stripe sensor for seam tracking

The design and manufacture method for optical system of laser-stripe sensor for seam tracking is researched,and this sensor is developed.When the optial system is in production,the wave-length should be measured at first,and then the filter is made.The experiment result shows that the sensor can filter the noise well and obtain seam images with high signal-noise ratio,which laid the foundation to enhance the real-time of seam tracking.
