A system for inspecting inner surfaces of cylindrical parts, comprising: a plurality of cylindrical parts having different inner diameters, each of said cylindrical parts including an inner surface extending circumferentially around a center axis and presenting a bore, said cylindrical parts supported by an arm rotating 360 degrees about said center axis; a camera with a lens disposed outwardly of said cylindrical part and axially aligned with said center axis of said cylindrical parts for acquiring images of said inner surface while said cylindrical part rotates 360 degrees about said center axis; said lens remaining in a fixed position while acquiring said images of said inner surface and while said cylindrical part rotates 360 degrees about said center axis; a light source disposed between the end of the cylindrical part adjacent said camera and said camera for directing light to said inner surface of said cylindrical part; said light source being a pair of light emitting diodes disposed opposite one another relative to said camera; a mirror disposed in said bore of said cylindrical part at a predetermined and fixed position along said center axis while said cylindrical part rotates 360 degrees about said center axis and while said camera acquires said images of said inner surface; said mirror including a mirror surface being disposed at a 45 degree angle relative to said inner surface for reflecting the light from said light source to said inner surface and from said inner surface to said lens of said camera; said mirror surface being disposed in a fixed position on said center axis relative to said inner surface of said cylindrical part while said cylindrical part rotates 360 degrees about said center axis; said camera being a line scan camera and each of said images being one dimension, wherein said mirror is spaced from said camera by a first distance (d 1) and spaced from said inner surface by a second distance (d 2), and a sum of said first distance (d 1) and said second distance (d 2) is fixed while said camera acquires images of said inner surfaces of each of said cylindrical parts. a plurality of cylindrical parts having different inner diameters, each of said cylindrical parts including an inner surface extending circumferentially around a center axis and presenting a bore, said cylindrical parts supported by an arm rotating 360 degrees about said center axis; a camera with a lens disposed outwardly of said cylindrical part and axially aligned with said center axis of said cylindrical parts for acquiring images of said inner surface while said cylindrical part rotates 360 degrees about said center axis; said lens remaining in a fixed position while acquiring said images of said inner surface and while said cylindrical part rotates 360 degrees about said center axis; a light source disposed between the end of the cylindrical part adjacent said camera and said camera for directing light to said inner surface of said cylindrical part; said light source being a pair of light emitting diodes disposed opposite one another relative to said camera; a mirror disposed in said bore of said cylindrical part at a predetermined and fixed position along said center axis while said cylindrical part rotates 360 degrees about said center axis and while said camera acquires said images of said inner surface; said mirror including a mirror surface being disposed at a 45 degree angle relative to said inner surface for reflecting the light from said light source to said inner surface and from said inner surface to said lens of said camera; said mirror surface being disposed in a fixed position on said center axis relative to said inner surface of said cylindrical part while said cylindrical part rotates 360 degrees about said center axis; said camera being a line scan camera and each of said images being one dimension, wherein said mirror is spaced from said camera by a first distance (d 1) and spaced from said inner surface by a second distance (d 2), and a sum of said first distance (d 1) and said second distance (d 2) is fixed while said camera acquires images of said inner surfaces of each of said cylindrical parts.
