Abstract: The present invention forms a metallic slit or an opening on a thin metal film and makes a surface plasmon antisymmetrically or symmetrically detached by the interference pattern of two incident lights having the same incident angle in opposite directions. A direction in which the surface plasmon is detached is switched as the relative phase difference between the two incident lights is adjusted.

Abstract: PURPOSE: A method and an apparatus for measuring the depth of a three dimensional object using multiple spatial frequencies are provided to simply and accurately measure the depth of a discontinuous three dimensional object without executing unwrapping algorithm. CONSTITUTION: An apparatus for measuring the depth of a three dimensional object using multiple spatial frequencies comprises a projector(10), a photographing unit(20), and a measuring unit(30). The projector scans lights, which correspond to a multi spatial frequency pattern including patterns according two or more spatial frequencies, to a three dimensional object. The photographing unit photographs the three dimensional object scanned with the lights and outputs a corresponding digital image signal. The measuring unit calculates the depth of the object based on the digital image signal.
