To erase a mask window, set Window/Mask to Window, specify the center
point, then move the cursor a distance equal to the radius. Next, click the left
mouse button, and an area equal to a circle of the radius through which the
cursor was moved will be erased.
To define another mask window, click on Add.
6.
Click on Inverse.
A reverse Fourier-transformed image will appear.
7.
Click on Exit to finish the FFT process.

3D Display
By displaying an image in 3-dimensional form, you can intuitively understand the
surface structure. This system enables you to display an acquired image in 3-dimensional
form.
1.
Click on 3D Display shortcut icon.
The 3-dimensional display window 3D Display and the 3D Display Properties
control panel appear.
Also, a 3-dimensional image is displayed in simplified form in the 3D Display
window.
2.
Set the display direction and position of the 3-dimensional display image.
Specify the rotation of a 3-dimensional image using Rotate in the Position tab, the
display magnification in the height direction using Z Axis, and the display position
using Centering.
3.
Set the display direction of a 3-dimensional display image.
Select Alpha overlay from Display Mode in the Display tab. Also, set Alpha Level
in the Option tab.
Setting the Alpha Level value to about 0.3 results in a biological surface image that
appears to have a wet surface. Setting it to about 0.7 results in a metallic surface
image that has luster.
4.
Set the surface characteristics of a 3-dimensional display image.
Select the Display tab, then set the surface characteristics of the 3-dimensional
image using Surface.
Set Diffuse level to about 0.5, Specular level to about 0.5, and Shininess to about
6.0.
The optimum values of these settings differ depending upon the displayed
image.
