# Camera working distance
# Scope: Pinhole object distance from sensor extent, focal length and field size.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

sensor = 6.4 mm
focal = 8 mm
field = 200 mm

distance := focal*field/sensor [mm]

check working distance budget: distance <= 300 mm

scenario alternative: sensor = 5.12 mm
