Title:
積分型光検出器を使用したフーリエ係数測定法
Document Type and Number:
Japanese Patent JP5548989
Kind Code:
B2
Abstract:
Provided is present invention a measurement method of Fourier coefficients using an integrating photometric detector, wherein, when measuring an exposure (S j ) 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 (±' 2n , ²' 2n ) 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 j ).
