气动加热对红外成像的影响试验研究

Experiment Research on the Aerodynamic Heating Effect on the Infrared Imaging

介绍了在气动加热条件对红外成像的影响试验研究的情况,利用电弧风洞产生高温,高超声速流场,模拟红外窗口的气动加热,红外图像由高温黑体产生,利用高速红外热像仪接收红外目标的辐射。通过对穿过高温流场、模型之后的红外图像测量分析,初步揭示了气动加热对光学传输的影响。

This paper provides an instruction of the experiment research on on the aerodynamic heating effect on the infrared imaging. With the high temperature hypersonic flow field generate by the arc heating wind tunnel, the infrared window was heated and the infrared image after transmit through the hypersonic flow field have been measured, with the analysis,we get the initial conclusion of the aerodynamic heating effect on the aero-opties（AO）.
