Abstract: PURPOSE: A 3D measuring device using coherent characteristics and a measuring method thereof are provided to obtain 3D images by using short-wavelength lasers or white lights depending on a size of an object and to acquire high quality images in short time regardless of the size of the object. CONSTITUTION: A 3D measuring device using coherent characteristics comprises a light source(100), a monochromatic filter(200), a beam splitter(300), a reference beam reflecting mirror(400), a measurement light reflecting mirror(500), and a photographing element(600). The monochromatic filter transmits lights of a constant wavelength from lights generated by the light source. The beam splitter divides the lights penetrated through the monochromatic filter into reference lights and measurement lights. The reference light reflecting mirror reflects the reference lights to the beam splitter. The measurement light reflecting mirror reflects the measurement lights to the beam splitter. The height of the measurement light reflecting mirror is adjusted. The photographing element obtains images by detecting the interference of the measurement lights and reference lights reflected to the beam splitter.
