Fig. 6.
The power spectra of Zernike modes of the wavefront aberration. The aberration was measured with paralyzed accommodation from one subject’s eye over a 6 mm pupil. The red, green, and blue curves are spectra of the 2nd, 3rd, and 4th order of the Zernike modes, respectively. The subject fixated on the left end of scanning line (the infinity). The power spectra are an average of the spectra of 10 series of time courses of the RMS wavefront aberration over 5 seconds. All the spectra of the Zernike modes were normalized with the maximum spectrum of the defocus ().
