An Opto-Electronic Integrated Non-Contact Angle Measuring System for Knife Blade Angle
in order to measure knife blade angle, which has a serious influence on the sharpness and sharpness retentivity of knives and scissors, a knife blade angle measuring system based on electronics and laser technology is established. This system has many advantages such as a high precision (±1°), convenient and simple operation, cost saving, non-contact, safety and stability, etc. The system is very helpful to improve the product qualities of knives and scissors.
