Abstract
Commonly used acoustic reconstruction algorithms for temperature fields assume that the sound wave paths between transmitter and receiver pairs are straight. When a sound wave passes through a nonuniform temperature field, the sound wave path will bend due to refraction. A comparison study on reconstruction accuracy with and without considering the bending of sound wave paths is conducted in this paper. First, obtain a reconstruction temperature field without considering the bending of sound wave paths. Then, find the sound ray paths in the reconstructed field by developing triangular method and acquire a reconstruction field with considering the bending of sound wave paths. Various single hot temperature fields are reconstructed from sound travel-time simulation data. Suggestions are given based on the analysis of reconstruction accuracy and feature of temperature fields.
