A METHOD FOR MEASURING RESOLUTION OF OPTICAL DEVICE

摘要

PURPOSE: A method for measuring the resolution of an optical device is provided to improve measuring accuracy and to obtain robust properties with respect to a measurement environment. CONSTITUTION: A method for measuring the resolution of an optical device is as follows. An angle is detected from an arbitrary target area of a test chart desired to measure the resolution(210). The detected angle data is oversampled at an unequal space(220). The oversampled data is resampled while filtering the same so that an equal space data is obtained(230). A primary difference of the equal space data is obtained(240). The intensity and a phase of frequencies are obtained by performing Fourier transformation with respect to the obtained primary difference data(250). The obtained intensity data is standardized(270).
