The scattered light pattern from a machined surface generally contains much information concerning the<br/>
surface roughness. The light pattern can be acquired by optical system and analyzed by statistical method.<br/>
This kind of surface roughness measurement system can be easily adopted on the machine measurement. But<br/>
the fully assembled system is too complex to implement on small systems using micro-controller. This study<br/>
proposes the idea of reducing the number of optical components by removing screen and examines image<br/>
processing of a light pattern to minimize the negative result of incomplete optical system. And the Gaussian<br/>
blur filtering is concluded to be the best method of proposed measurement system. Furthermore light intensity<br/>
variation of image pattern can be treated as a signal, therefore FIR filtering gives the similar result of<br/>
Gaussian blur effect.
