Parametric study on single-camera endoscopic tomography

Abstract

Optical tomography has become an indispensable tool for combustion diagnostics due to its noninvasiveness. However, for a typical tomography system, multiple high-speed cameras are usually required to capture different perspectives simultaneously, which is costly and requires precise synchronization, especially for the diagnostics of supersonic/hypersonic flows. Recently, a single-camera endoscopic tomography system has been proposed to overcome the aforementioned problem [Opt. Commun. 437, 33 (2019) [CrossRef]  ]. This work aims to optimize the parameters of the single-camera tomography system such as the number of input ends of the fiber bundle and focal length of the lens. Simulative and experimental studies were conducted. The results show that it has the best performance to register nine projections onto a single camera.
