红外（IR）光谱成像技术在2000年代中期似乎已经成熟，在商业上取得了成功，并且在许多应用中都有报道。然而，最近的发展已经改变了我们对记录数据的理解，为新的仪器提供了能力，并且大大增强了在更短的时间内提取更多有用信息的能力。这些发展在这里概括为三个广泛的领域-数据记录，记录数据的解释和信息提取-他们的批判性审查被用来预测新趋势。总的来说，从硬件、理论、算法和应用中选择组件的融合是一个趋势。代替类似的通用仪器，另一个趋势可能是由新兴组件技术驱动的多样化和面向应用的仪器设计。最近基础科学和仪器仪表的复兴可能会刺激传统光谱分析和光学物理的融合研究，以改进数据解释。虽然化学计量学已经主导了数据处理，但在传统化学计量学分析之前，信号处理算法的发展可能是一个趋势，以最佳方式提取光谱和空间信息。最后，这些最新进展的总和很可能提供前所未有的测量能力和科学洞察力，这将为应用光谱学家提供新的机会。
Infrared (IR) spectroscopic imaging seemingly matured as a technology in the mid-2000s, with commercially successful instrumentation and reports in numerous applications. Recent developments, however, have transformed our understanding of the recorded data, provided capability for new instrumentation, and greatly enhanced the ability to extract more useful information in less time. These developments are summarized here in three broad areas— data recording, interpretation of recorded data, and information extraction—and their critical review is employed to project emerging trends. Overall, the convergence of selected components from hardware, theory, algorithms, and applications is one trend. Instead of similar, general-purpose instrumentation, another trend is likely to be diverse and application-targeted designs of instrumentation driven by emerging component technologies. The recent renaissance in both fundamental science and instrumentation will likely spur investigations at the confluence of conventional spectroscopic analyses and optical physics for improved data interpretation. While chemometrics has dominated data processing, a trend will likely lie in the development of signal processing algorithms to optimally extract spectral and spatial information prior to conventional chemometric analyses. Finally, the sum of these recent advances is likely to provide unprecedented capability in measurement and scientific insight, which will present new opportunities for the applied spectroscopist.
