Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
An on-line scanning sensor system for detecting characteristics of sheet materials by spectrometric methods comprising: a frame means having first and second horizontally extending guide members connected by side members to define a rigid box-like frame; support means for supporting the frame means; vibration-absorbing suspension means for suspending the frame means from the support means such that vibrations are substantially attenuated between the frame means and the support means; first carriage means mounted on the first guide member for scanning motion across a traveling sheet of material; interferometer component means mounted to be carried by the first carriage means, the interferometer component means including means for splitting and recombining infrared light and for directing a collimated beam of the recombined light onto a traveling web of sheet material; and detector means for receiving light from the interferometer component means as it travels during scanning across a traveling sheet.
Claim 2
Dependent Claim
