Abstract
Liquid crystal thermography (LCT) generates two-dimensional temperature information in a fluid layer. A three-dimensional temperature field can be reconstructed using the two-dimensional temperature fields obtained at various locations with the help of synchronized movements of the light sheet and camera. However, in many cases it may not be feasible to generate a large number of two-dimensional liquid crystal thermographs that are needed to represent a high-resolution, three-dimensional temperature field. In the present article, a tomographic reconstruction method is suggested that can be used to produce a high-resolution, three-dimensional reconstruction from a limited number of two-dimensional images of the full temperature field. The two-dimensional temperature fields generated from the LCT experiments can be used to obtain integrated information of the three-dimensional field from various directions. These estimated projections of the actual three-dimensional field can be used to reconstruct a high-resolution volumetric temperature field within an acceptable error.
