Example 4: Picking the best laser exposure
Exposure: 0
Exposure: -1
Exposure: -2
Exposure: -3
As we experiment with different laser exposures for this wooden
block, pictured to the left, the wrong choices are apparent.
Exposures 0, -1 and -5 all give broken lines with lots of gaps.
Removing them leaves -2, -3 and -4, and they’re all comparable. So
how do you choose the “best” of two or three exposures when they
are more or less the same? The best choice in a case like this is to
choose the highest value exposure, which in this case is -2. As a
rule, when more than one exposure gives good results, choose the
highest value one, as it will often let the scan go faster, and also
reduces data found on the scan bed.
Exposure: -4
Exposure: -5
