The 3D surface topology of turbulent diffusion flames is reconstructed and visualized using stereoscopic methodology. The basic stereo apparatus used in present study consists of a high-resolution digital camera and a stereo adapter, which is mounted to the front filter ring of the camera. A pair of stereo images therefore could be formed through the same lens system and recorded simultaneously on the same charge coupled device (CCD) chip. The digitally reconstructed 3D results have also been validated by optical stereoscopic viewing using a pair of electronic shutter glasses synchronized with computer monitor. The results have demonstrated that the technique is a very powerful diagnostic tool in combustion studies.
