Claim:
1. A method of generating a tomographic image, the method comprising: generating an optical signal having a wavelength; splitting the optical signal to measure a target object; detecting an interference signal including cross-sectional information of the measured target object, as raw data of the target object, the raw data being phase-modulated in a first direction with respect to a cross section of the target object; demodulating the raw data by adjusting at least one parameter of a filter function defining filtering within a fixed window size to output a demodulated raw data signal; and generating a tomographic image of the target object by performing signal processing on the demodulated raw data signal, wherein the parameters of the filter function include a duration and a roll-off, and wherein the filter function comprises a coefficient defined by a product of
