Abstract

This work describes instantaneous three-dimensional (3D) flame measurements using fiber-based endoscopes (FBEs). The measurement technique used FBEs to gather projections of the target flame from various orientations simultaneously, based on which a 3D tomographic reconstruction was then performed to obtain 3D flame measurements. Both experimental and numerical results are reported to illustrate the capabilities of the measurement technique, and study its limitations. These results demonstrate the feasibility of obtaining instantaneous 3D measurements with sub-mm spatial resolution at kHz temporal resolution using FBEs, and also the practical advantages of FBEs for overcoming optical access and reducing equipment cost.
