将剪切干涉法用于温度场的测量 ,通过对干涉图像进行处理 ,得到了电阻丝周围温度场的分布。将高速摄影技术用于火花点火发动机燃烧过程的研究 ,拍摄到发动机整个燃烧室内火焰的连续剪切干涉图像。通过对图像进一步处理 ,可以定量得到燃烧过程中不同曲轴转角的缸内温度场。
The shear interference method is used to measure the temperature field. By processing the interference image, the temperature distribution around the resistance wire is obtained. The high-speed photographic technology for the spark ignition engine combustion process research, capture the entire engine combustion chamber flame continuous shear interference image. By further processing of the image, the in-cylinder temperature field of different crank angles during combustion can be quantitatively obtained.
