光学系のレスポンス函数測定法の研究

抄録

Response function of an optical system is represented completely by the amplitude and phase characteristics with respect to spacial frequencies. For measuring these characteristics simultaneously and quickly, a new method is suggested, in which a sinusoidal grating with varying constant, a mechanical cam for scanning with varying velocity and pulse circuit for phase detection are employed. Applying this method, a measuring apparatus for practical use has been designed and constructed, and its performance is described.
