Develop A New Type Apparatus for Measuring Inner Diameter of Gun Barrel Using Optical Grating Sensor

Abstract

In aimed at the technic actuality of measuring inner diameter of gun barrel, we set forth a technique for improving precision of measuring inner diameter of gun barrel. The optical grating measuring apparatus developed has overcome the limitation of traditional optical grating measuring apparatus, and has resolved the puzzle of inaccurate count for traditional optical grating measuring apparatus. The results show that measuring technique using optical grating sensor has extensive application foreground.
