This is the governing equation for many object and image plane
parameters.
Exampl e: A n acquisition system has a 512 x 512 element, 10µm pixel pitch area scan
camera, a l ens w ith an effecti v e focal length of 45mm, and requires that 100µm in the
object space cor r espond to each pixel in the image sensor. Using the preceding equation,
the object distance must be 450mm (0.450m).
