d. Division: /
e. Exponentiation: h or$
2. A formula must specify the analog result from at least
one SLS, as follows:
a. SLS 1: laand lb
b. SLS2: 2aand2b
c. SLS 3: 3a and 3b
d. SLS4: 4aand4b
Thus, la is the analog A output from SLS 1, and 4b is the
analog B output from SLS 4.
In both of the following examples, assume that the SLS is
configured with the 1-D Spatial Measurement function.
Example 1: (2b - la)
This formula causes the difference between the analog B
output (last edge) from SLS 2 and the analog A output (first
edge) from SLS 1 to appear in the designated chart.
If each SLS were each positioned to locate one end of a
long item, and the result values from each SLS were
calibrated to the same “real world” units, this formula
would indicate the actual length of the item.
Example 2: ((lb - la)“2 + (2b - 2a)*2)“0.5
This formula uses the Pythagorean theorem to calculate the
diagonal measurement across a rectangle. It causes the
square root of the sums of the squares of the differences
between the two sets of edges to appear in the designated
chart. Each “difference” represents a distance between a
first edge and a last edge within the same field of view.
Thus, (lb - la) is the distance between the fmt and last
edges within the FOV of SLS 1.
If the two SLS’s were positioned to measure the length and
width of the same rectangular item, and the results values
from each SLS were calibrated to the same “real world”
values, this formula would indicate the diagonal distance
across the rectangle.
