THE METHOD AND DEVICE FOR ADJUSTING INCIDENT LIGHT INTENSITY AND ESTIMATING REFLECTED LIGHT COMPONENTS WITH A REFLECTED LIGHT IMAGE INFORMATION FEEDBACK ON A LASER SURFACE ROUGHNESS MEASUREMENT

摘要

The present invention, the laser beam control method at the time of surface roughness measurement using Image information feedback according to the present invention relates to a laser control method and a surface of the laser light control device for a roughness measurement of the time of surface roughness measurement using Image Feedback Laser for the surface roughness measurement of the object 1) and the regularly reflected light reflected from the subject, and I from the optical data phases each of the optical data of the reflected light is obtained on the image sensor 2) measuring the surface roughness of the object, using the through the correlation calculated by the degree of light intensity and irregular reflection of light diffusion of the regular reflection method comprising blending the respective reflected light 3) normalizing the light intensity of the blended light reflected by setting the reference 4) of the normalized reflected light receiving an optical data input controls the laser beam source with a laser beam incident to the object and It characterized by comprising the steps:; Laser control method and a control device at the time of surface roughness measurement using Image information feedback according to the present invention has the effect of appropriately adjusting the incident light when measured surface roughness and accurately obtain the light intensity change in the regularly reflected light, the surface roughness calculation formula to the effect that can be unified against the smooth surface and rough surface.
