They also demonstrated that the probe could acquire
separate coherent anti-stokes Raman scattering, second harmonic generation and two - photon excited autofluorescence images
of healthy human skin tissue samples with a resolution
of 2048 by 2048 pixels for a scanned area
of 300 by 300
microns.
While the current impasse
of air credits focuses on PM - 10, there are plans to create a
separate and distinct particulate matter less than 2.5
microns in size (PM - 2.5) standard, which would likely be the focus
of emission compliance issues for power plants.
