Measurement of Roughness Surface Using Optical Chromatic sensor

The advance in manufacturing automation has created the need to develop in measurement of surface roughness. There are many challenges in surface roughness measurement, such as precision and anti-jamming performance of measurement. Introduced a chromatic sensor based on chromatic aberration and analyzed the work principle of non-contact measurement for surface roughness using chromatic sensor. This method for non-contacted measurement of surface roughness is not only helpful to quick, nondestructive measurement but also helpful to increasing precision and anti-jamming. The theoretic principles of non-contact measuring surface roughness based on chromatic aberration and chromatic sensor have been introduced, and the working principle of chromatic sensor has been analyzed. Experiments have been done to prove the theoretic.
