Patent number: 10481100Abstract: Increasing the precision of process monitoring may be improved if the sensors take the form of traveling probes riding along with the flowing materials in the manufacturing process rather than sample only when the process moves passed the sensors fixed location. The probe includes an outer housing hermetically sealed from the flowing materials, and a light source for transmitting light through a window in the housing onto the flowing materials. A spatially variable optical filter (SVF) captures light returning from the flowing materials, and separates the captured light into a spectrum of constituent wavelength signals for transmission to a detector array, which provides a power reading for each constituent wavelength signal.Type: GrantFiled: April 12, 2018Date of Patent: November 19, 2019Assignee: VIAVI Solutions Inc.Inventors: Benjamin F.
