Patent application numberDescriptionPublished
20100273331METHOD OF FABRICATING A NANO/MICRO STRUCTURE - A method of fabricating a nano/micro structure comprising the following steps is provided. First, a film is provided and then a mixed material comprising a plurality of ball-shape particles and a filler among the ball-shape particles is formed on the film. Next, the ball-shape particles are removed by the etching process, the solvent extraction process or the like, such that a plurality of concaves is formed on the surface of the filler, which serves as a nano/micro structure of the film.10-28-2010
20100284022DISPLACEMENT MEASUREMENT SYSTEM AND METHOD THEREOF - A displacement measurement system including a coherent light source, a two-dimensional grating, a photo sensor, and a signal processing apparatus is provided. After the coherent light beam enters the two-dimensional grating, a zero-order light beam and a plurality of first-order diffraction beams are generated. The zero-order light beam interferes with two of the first-order beams in different directions, so that corresponding interference fringes are formed on the photo sensor. Accordingly, when the two-dimensional grating moves, displacements of the two-dimensional grating in the different directions are obtained by calculating phase differences of the interference fringes in the corresponding directions. Besides, when the two-dimensional grating rotates, the rotational angle of the two-dimensional grating is obtained from the corresponding rotational angle of a diffraction pattern of the first-order diffraction beams.11-11-2010
