Measurement of fourier coefficients using integrating photometric detector |
摘要 |
<p>Provided is present invention a measurement method of Fourier coefficients using an integrating photometric detector, wherein, when measuring an exposure (S<Sub>j</Sub>) with a predetermined time interval during a predetermined time period using an integrating photometric detector with respect to light of which amplitude varies with the time period, normalized Fourier coefficients (α'<Sub>2n</Sub>, β'<Sub>2n</Sub>) for a waveform of an intensity of the light is determined by carrying out a discrete Fourier transform with respect to an equation for the measured exposure (S<Sub>j</Sub>).</p> |
