Tilt in the lateral axis
The optical sensor head is tilted around its lateral axis by 5 to 10° (Fig. 10
(II)). The reflected light does not reach the receiver. Almost all the light is
reflected into the reflective direction at a glossy mark. The reflective reflec-
tions are hardly detected by the receiver. Only the diffuse part of the matte
background is detected by the receiver. Only a small part of the light from
the diffuse background reaches the receiver as compared to the place-
ment in figure Fig. 9.
• Advantage: The distances between transmitter and background, as well
as between receiver and background, are identical. The optical sensor
head can be aligned easily.
• Disadvantage: Only little light is reflected into the receiver.
