一、引言 TED探测器的出现对英国热成象技术的发展有着较大的推动作用。最佳利用这些探测器的成象系统的设计考虑与普通探测器很不相同。本文的第一部分是推导出TED探测器的理论模型,器件长度和读出区几何形状影响的考虑。用这个模型的一种稍微简化的形式来具体
I. INTRODUCTION The emergence of TED detectors has greatly promoted the development of thermography in the United Kingdom. The design considerations that best make use of these detectors' imaging systems are very different from those of normal detectors. The first part of this paper is to deduce the theoretical model of the TED detector, the length of the device and the geometry of the readout area. In a slightly simplified form of this model to specific
