Correlation between sensing object size and sensing range
As the sensing object size
becomes smaller than the
standard size (white non-glossy
paper 50 × 50 mm 1.969 ×
1.969 in), the sensing range
shortens, as shown in the left
graph.
For plotting the left graph,
the sensitivity has been set
such that a 50 × 50 mm 1.969
× 1.969 in white non-glossy
paper is just detectable at a
distance of 100 mm 3.937 in.
