ABSTRACT:
An on-line scanning sensor system includes first and second horizontally extending guide members connected by side members to define a rigid box-like frame, and a support structure for suspending the box-like frame via vibration-absorbing devices such that vibrations are substantially attenuated before reaching the guide members. Further, the system includes a carriage mounted on the first guide member for scanning motion across a traveling web of sheet of material, and interferometer components mounted to the carriage for splitting and recombining infrared light and for directing a collimated beam of the recombined light onto the traveling sheet. Still further, the system includes a detector for receiving light from the interferometer components during scanning.
