Readout Density Cross Scans

Pixel Sampling Density Scan

fixed field divided finer

A fixed image field becomes different pixel lengths as count changes. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Few pixels make a coarse sampling length

Image length 12 m divided with 3 pixels, each pixel is 4 m.

More pixels shrink the pixel length

with 6 pixels, each pixel is 2 m. The image length stays fixed.

Double again halves the pixel length again

with 12 pixels, each pixel is 1 m. This is sampling density only, not optical resolution.
