Fitting

2012-03-14T15:19:56+03:00

Fitting Often images obtained by AFM have the common slope or the common salience. Such distortions can appear for different reasons. As a rule, they are related to the temperature drift and the non-linearity of the piezoceramic manipulator. This macroscopic surface pattern usually prevents definition of the object’s structure.

Spline fitting

2012-03-14T15:19:56+03:00

Spline fitting Often the surface pattern and distortions that may occur because of the non-linearity of the piezoceramic manipulator as a whole distort the image in such a way that the subtraction of the surface of the second order does not make it vivid enough. FemtoScan software can form bilinear cubic splines for surfaces and subtract splines from surfaces. To subtract a spline please select the

The program is primarily focused on working with the SPM data - three-dimensional surface profile, force curves, arrays of force curves. The better you know the methods described here - the faster and easier you will obtain success in your work with SPM.

Parameters The menu item View -> Parameters is intended to show scanning parameters from the file. The list of parameters may be different depending on the data format.

Resolution

Resolution If by some reason horizontal or vertical scale of the image is misrepresented, you are able to correct it. Use menu command View -> Resolution to do it. It is availiable if a surface image, curve, section, or histogram is active. If you use

Actual pixels

Actual pixels When you run the menu command View -> Actual pixels or press the tool bar button , an activ image will be replotted in its real size, as 512*512 pixels, for example. If an image is zoomed in or zoomed out, it will be written in the header in percents:

Normalize

2012-06-26T12:41:11+03:00

Normalize The standart image size in SPM is 512*512 pixels. Undoubtedly some images are bigger while others are smaller. But if you work with a standart screen resolution, it is convinient to work with images of 512*512 pixels. The menu item View -> Normalize

Z scale
