红外探测器成像仿真

Imaging Simulation of Infrared Detector

红外探测器是红外成像技术的核心,直接影响着红外成像系统的性能。在分析目标成像尺寸的基础上,详细分析光学弥散、探测器噪声、成像阵列盲元等的形成机理,并进行建模和仿真,最后将这些模型依次叠加。采用此方法得到的仿真图像充分考虑了探测器各种效应的影响,提高了仿真图像的真实性与逼真度,可为红外成像系统的研制及目标检测识别算法提供测试场景与依据。

Infrared detector, which can directly influence the performance of infrared imaging system, plays a key role in infrared imaging technology. The scale of the target image, the causation of optics dispersion, noise of the detector and blind pixels in the imaging arrays were detailed analyzed. More actual infrared images would be simulated by adding the effects mentioned above to the theoretical image model, because the ill effects were calculated. The simulated images could be used to test infrared imaging system or the algorithm of target detecting and recognition.
