DISPLAYING THE MEASUREMENT RESULT
(1) Mire Image (Scotopic)
(See "Mire image" on page 79.)
The data with the largest pupil diameter measured by Scotopic is dis-
played.
In the Mire image, angle scale, pupil frame (Scotopic and Photopic)
and pupil center position are overlay-displayed in colors (Scotopic:
yellow, Photopic: green). Overlay information can be set to ON/OFF.
(2) Difference Information
As difference information, pupil diameter by Scotopic and Photopic,
deviation of center coordinates (distance @ direction) and SCA cal
-
culated from wavefront aberration are displayed.
(3) RMS (4mm/pupil diameter), Simulation (pupil diameter, 4th-order)
From the data of three measurements performed by Scotopic and
Photopic respectively, one result is selectively displayed. Measure
-
ment data can be changed by tapping the
displayed at the upper part.
(According to the selected data, information of (1) and (2) are
updated.)
For each data, HOA map, RMS (4mm/pupil diameter), Simulation
(4th order) dealing with pupil diameters up to 4mm as the analysis
range, and the date of measurement are displayed.
(4) Data Feed button Moves to the analysis result to the next data, or returns to the previ-
ous data. (The information on (1), (2) and (3) is updated according to
the selected data.)
Operation: • When tapped, the image is enlarged. (See "ENLARGEMENT DIS-
PLAY" on page 94.)
• When dragged in the right direction, the overlay can be changed.
• TOPO MAP overlay can be displayed.(See page 100.)
Overlay information can be set to ON/OFF on the SETTINGS
screen "DISPLAY". See page
145.
Simulation deals with pupil diameters up to 4mm as the analysis range. Even
when the pupil diameter is 5mm or more, the maximum analysis area is 4mm.
For the Mire image, the pupil overlay is not displayed when the setting is OFF. To
enable the overlay, tap the
of the set item display "Pupil
Detection overlay" of the SETTINGS screen "DISPLAY," and tap and select "ON"
