How it Works
The CI 202 measures length, width, area, and perimeter, and calculates ratio and shape factor once a measurement is completed.Each time the control unit detects that the laser scanner has progressed 1 mm, the computer checks to see if the width reading is non-zero. If the width measurement is non-zero, the computer takes the following actions:

The length measurement is increased by 1 mm.
The width measurement is added to the area accumulator.
If the width measurement is greater than the currently stored maximum width, the maximum width is updated.

Aspect ratio is the ratio of the leaf length to its maximum width:Shape factor is the ratio of the leaf area to the leaf perimeter, corrected so that the shape factor of a circle is equal to 1:
