Fig. 2. Temperatures recorded by Neoptix fiber-optic sensors during RF treatment of white ash decking boards with no added pressure. Probes located in the workload had the ISPM-15 reached 60 °C for 1 min. after 269 min of treatment.

Fig. 3. Left thermal image (older FLIR Model T250 camera) shows the heating consistency of 4”x6” cants and the same post-treatment results for the stringers (right image). The right image used a newly acquired FLIR model T530 camera. Note: Despite differences in appearance, both images are the same emissivity (ε= 1.00) value as camera calibrations for thermal reading sensitivity.

Fig. 4. The figure represents the treatment duration for consecutive experiments performed on white pine cants.
