Precision noncontact measurement of the print-through phenomenon (PTP) of the fiber-reinforced plastics (FRP) is an urgent problem to be solved in yacht industry, especially for the quantization of the surface roughness and the profile of the yacht surface with PTP. The study presents the development of a surface profile measurement system using a fringe reflection method on a PC-based 3-axis measuring machine. The developed system mainly consists of a PC-based 3-axis machine, a CCD Camera, a programmable liquid crystal display (LCD) as a fringe projector, a screen on which the reflected fringe would be projected, a set of measurement software, and a PC. The surface roughness and the 2D profile of the flat composite specimens with PTP could be measured simultaneously using the fringe reflection method, based on the calibration results. Two-dimensional profile of a specimen with PTP was determined by the triangulation principle. The surface roughness of a test object was determined based on the scattering principle.
