Option 1
1. Calculate the conveyor movement that will generate six encoder steps:
2. Calculate the magnification needed to make 1.2 mm of conveyor movement result in 112 µm
movement of the image:
3. Calculate the width of conveyor that will be viewed by each sensor line at this magnification:
Option 2
1. Calculate the conveyor movement that will generate seven encoder steps:
2. Calculate the magnification needed to make 1.4 mm of conveyor movement result in 112 µm
movement of the image:
3. Calculate the width of conveyor that will be viewed by each sensor line at this magnification:
As you can see, if you choose to use six encoder steps (option 1) to move the image 112 µm, you
will require a 1:10.72 magnification and at this magnification, the field of view of each sensor line
will be 314.87 mm. If you choose to use seven encoder steps (option 2) to move the image 112 µm,
you will require a magnification of 1:12.5 and at this magnification, the field of view of each sensor
