Reflection angle
Depending on the reflection angle, the reading Depending on the reflection angle, the reading
may be distorted.
Point A in this example may not be detected. in this example may not be detected.
Reflection angle
Surface a is closer to the sensor than surface is closer to the sensor than surface
b, but surface b has a better reflection so it will
be detected first whereas surface a may not be be detected first whereas surface

Point C may not be detected when the surface may not be detected when the surface
