What is the frequency of a grid with lead strips that are 33 micrometers thick and interspace material that is 310 micrometers thick?
What will be an ideal response?
74 lp/inch
There are 10,000 micrometers per centimeter.
The total thickness of the grid strip and interspace material is 33 micrometers + 310 micrometers for a total of 343 micrometers per line pair.
Divide the line pair thickness into 10,000 micrometers/cm which yields 29.15 lp/cm
Convert this to inches by multiplying 29.15 by 2.54 cm/in
This product is 74.04 lp/inch
