Abstract
Focus variation is an optical contact-free method that allows the measurement of three-dimensional surface metrology using optics with limited depths of field and vertical scanning. It was documented in the ISO 25178-6 first time in 2010.As one method of image capture, it has very crucial influence to get an excellent quality image that some key parameters are selected correctly for different workpiece. Those key parameters are including the exposure time, contrast, filters and so on. In this paper, a few of applications were selected to demonstrate the capabilities of the system using different measurement parameters including measurements on cutting-insert tool, stainless steel ball, stepped workpiece and VDI standard workpiece with silver colour surface. Some principles were concluded for optical three-dimensional surface measurement with focus variation after comparing the practical results with different parameters, serving as measurement strategies.
