Changing  the field of view does  not  affect  the  physical  motion  of the servo as this  would  upset  the  PWM  and  servo lag settings. 
Instead, the field of view cuts out unwanted data from the edges of the scanned image. The left and right edge settings of the field 
of view can be changed independently.

For high precision scanning, the servo can be made to scan in one direction only. The resulting image has higher angular repeatability 
at the expense of increased power consumption by the servo when returning to the start of the scan. Switching from bi-directional to 
uni-direction scans is done using the “Scan type” selection box.
