Calibration of the Field of View Directional Response Function of Infrared Spectroradiometers
-
摘要: 在红外辐射特性测量领域，傅里叶变换红外光谱辐射计为常用测量单元，其视场方向响应特性为主要不确定度来源之一，表现为：随着测量目标偏离视场中心，不同位置的响应度出现差异。目前针对视场方向响应的研究所采用的辐射源多为中温常规尺寸黑体，空间分辨率有限。采用高温小尺寸黑体辐射源开展傅里叶红外光谱辐射计视场均匀性研究，获得75mrad典型视场下方向响应函数；分析了视场均匀区光谱响应度的变化规律，提出针对视场方向响应特性的修正函数，并进行实验验证。结果表明：视场均匀区经本文所提出的修正函数修正后，响应度均匀性由92%提升至98%。Abstract: In the field of infrared radiation characteristics measurement, Fourier transform infrared (FTIR) spectroradiometers are commonly used measurement units. The field of view (FOV) directional response function is one of the main sources of uncertainty, which manifests as varying responsivity at different locations when the measurement target deviates from the center of the FOV. Currently, most studies on FOV directional response employ medium-temperature, conventional-sized blackbodies as radiation sources, resulting in limited spatial resolution. In this study, a high-temperature, small-sized blackbody radiation source is used to investigate the FOV uniformity of FTIR spectroradiometers, and the directional response function under a typical FOV of 75 mrad is obtained. The variation of spectral responsivity in the uniform region of the FOV is analyzed, and a correction function for the FOV directional response characteristics is proposed and experimentally verified. The results show that after applying the proposed correction function, the responsivity uniformity in the uniform FOV region increases from 92% to 98%.
