ABSTRACT
Blackbody radiation is standardised electromagnetic energy emitted into space at a given temperature and wavelength distribution. It is used as a reference model to compare radiation emitted from various objects. This reference performance of blackbody systems should be maintained through periodic inspection and calibration. In this study, temperature uniformity on the surface of the blackbody was evaluated using infrared cameras. To this end, we divided the blackbody system measurements into ‘before’ and ‘after’ calibration sets and examined the blackbody surface in different bands, using two infrared cameras with different measurement principles. To evaluate surface temperature uniformity, we calculated the signal transfer function, equivalent noise temperature difference, and 3D noise of the infrared detector, and then comparatively analysed them.

红外热像仪评价黑体表面温度均匀性的实验研究
摘要
黑体辐射是在给定温度和波长分布下发射到空间中的标准化电磁能。它被用作参考模型来比较各种物体发出的辐射。黑体系统的这种参考性能应通过定期检查和校准来保持。在这项研究中,使用红外相机评估了黑体表面的温度均匀性。为此,我们将黑体系统测量分为“之前”和“之后”校准集,并使用两个具有不同测量原理的红外相机在不同波段检查黑体表面。为了评估表面温度均匀性,我们计算了红外探测器的信号传递函数、等效噪声温差和 3D 噪声,
