The simultaneous measurement of spatially resolved stereoscopic velocimetry temperature is valuable for characterizing flows pertinent to combustion and hypersonic environments. We have extended the previously demonstrated VENOM (Vibrationally Excited Nitric Oxide Monitoring) technique in high speed gas flow fields to the out-of-plane component. Previous reports have demonstrated VENOM as a viable technique to simultaneously characterize two dimensional velocity and temperature. We present three dimensional velocimetry and two dimensional temperature using 2.5% NO<sub>2</sub> in N<sub>2</sub> in a pulsed Mach 6.2 flow nozzle. This was accomplished using two additional angled ICCD cameras to capture the time-delayed images and by developing the necessary image processing algorithms. A well calibrated out-of-plane flow was generated using a small aluminum wedge in a uniform high speed flow will be presented.
