The phase spectrum is not available for the responses of systems whose
output is integrated over time. A temporal deblurring technique has b
een described for measurement of the phase spectrum for responses that
are based on the integrated output of such systems [Vision Res. 21, 4
09 (1981)]. The problem that remains is to determine the optimal sets
of Fourier amplitudes to be used for the phase-reconstruction task. Op
timal Fourier amplitudes for determination of the phase of each harmon
ic have now been obtained for relevant weighting functions by an analy
tic method and by a computation method up to the 20th harmonic. These
amplitude sets should permit efficient use of the temporal deblurring
paradigm to measure the impulse response of any integrated output syst
em that is linear up to the integration stage.
