Noncontact Angle Measuring System Based on Laser and Capacitive Sensor
Based on laser and capacitive sensor, a method of measuring deflectable angle is presented, and a noncontact angle measuring system is established. This system has the advantages of simple constitution, real-time, on-line measuring, non-contact and high precision. It can be widely used in engineering, especially in blade angle detection of knife and scissors.
