b) Fourier analysis map
The Fourier analysis map performs Fourier analysis
for refractive powers at individual measurement points
obtained by analyzing Mire images within the
f
3 mm
range (rings 1 to 9) and
f
6 mm range (rings 1 to 20), and
visually and quantitatively displays the constant term, the
first order term, the second order term, the higher order
terms.
(1) Original map and Stats data display area
An ordinary single map is shown at a reduced size.
Almost the same options as those for the single map
display are available.
(2) Fourier map display area
The constant term, the first order term, the second
order term, the higher order terms.
(3) Fourier index display area
Individual component values of
f
3 mm/
f
6 mm are
shown numerically.

Fourier Map.”)
