傅里叶变换红外显微光谱 (FTIRM) 和成像 (FTIRI) 已成为在微观尺度上检查材料化学成分的有价值的技术。大多数红外显微镜都配备了传统的热（全球）红外源和单元件（点）探测器。最近，通过使用同步加速器光作为红外光源，红外显微光谱的空间分辨率得到了显着提高。此外，通过一维和二维焦平面阵列探测器的实施，该技术的数据收集率也大大提高。红外光源和探测器的选择很重要，并且取决于特定的应用。在这项工作中，我们展示了传统全球红外光源和同步加速器光之间以及单点探测器和焦平面阵列 (FPA) 之间的差异。这些比较为根据应用类型选择优选的红外源和探测器提供了指导。 (c) 2005 Elsevier B.V. 保留所有权利。
Fourier transform infrared microspectroscopy (FTIRM) and imaging (FTIRI) have become valuable techniques for examining the chemical composition of materials on a microscopic scale. Most IR microscopes are equipped with conventional thermal (globar) IR sources and single-element (point) detectors. Recently, the spatial resolution of IR microspectroscopy has been dramatically improved by using synchrotron light as the IR source. Also, the data collection rates of the technique have radically increased through the implementation of one- and two-dimensional focal plane array detectors. The choice of IR source and detector is important, and depends on the particular application. In this work, we show the differences between conventional globar IR sources and synchrotron light, and between a single-point-detector and focal plane array (FPA). These comparisons provide guidance for the preferable IR source and detector based on the type of application. (c) 2005 Elsevier B.V. All rights reserved.
