摘要： Provided is an apparatus for measuring a three-dimensional profile using a LCD in which a sine wave pattern is formed on a measurement object, whereby image information of the measurement object is obtained using the sine wave pattern and a camera, and the image information is analyzed to measure a profile of the measurement object, the apparatus including a LCD projector including: a light source irradiating light forward; a LCD panel disposed at a front side of the light source, generating a sine wave pattern having a plurality of phases and a plurality of periods; polarization plates respectively disposed on front and rear sides of the LCD panel; a first focusing lens disposed apart from a front side of the LCD panel, focusing the sine wave pattern generated by the LCD panel on the measurement object; and a housing supporting the light source, the LCD panel, the polarization plates and the first focusing lens.
