모아레간섭을 이용한 3차원 형상측정

This paper presents appliation of optical moire topography to mesuring force profiles of dies and clay models for practical use in the field of production engineering. Moire topography has been studied intensively during last few decades in the area of optical physics and its mathmatical theory has now been established. In this study, two optical configurations are suggested in which resultant moire fringes can be readily analyzed, so that 3D proviles of the models are constructed through a series of image processing by suing ma chine vision techniques. Experimental results demonstreated by using a micro- computer and CCD camera show 0.05mm measuring spatial resulution, so that the optical method can effectively adopted in order to overcome many difficulties arising when using the existing contact-type digitizing methods.
