Figure 7-50: Aberrometry acquisition, during the "Fogging" phase
After each image has been acquired and the elapse of the time required to process
the map, the
acquired image
in Figure 7-51 displays.
The left section of this screen shows the image acquired by the sensor, the
dimension of the pupil only (IR), measured in the mesopic-scotopic conditions of
the test, and the refraction measured at a pupil size, that can be selected using the
methods described in section §7.6 (Figure 7-43 and Figure 7-44).
The right section of the screen shown in Figure 7-51 shows the map of the wave
front. By pressing the buttons under the map, it is possible to choose whether to
display the high orders [High] of the Zernike polynomials, the low ones [Low], all the
orders [All] or the high orders with astigmatism [High+Astigm.].
Figure 7-51: Aberrometry, acquired image: results
The gradation of colours in the map of the wave front can be changed as shown in
Figure 7-45.
It is also possible to locally change the Rx refraction options, as shown in Figure
7-46, Figure 7-47 and Figure 7-48.
