Number: 356/429
Name: Optics: measuring and testing > By monitoring of webs or thread
Description: Subject matter for inspecting or testing webs or threads of material including apparatus to support and transport the web under, over, or through an inspection station; a light source with optical means (which may include flying spot scanners) to direct the light through, around, or reflective from the web or thread; visual and photoelectric means (including comparator types) to detect changes in the light intensity produced by the light coacting with the web or thread; and with the photoelectric alternative an indicator responsive to the photoelectric means to not quantitatively or qualitatively variations in optical properties or condition.
