In the mid-infrared (MIR) spectral range, a series of applications have successfully been shown in the fields of sensing, security and defense, energy conservation, and communications. In particular, rapid and recent developments in MIR light sources have significantly increased the interest in developing MIR optical systems, sensors, and diagnostics especially for chem/bio detection schemes and molecular analytical application scenarios. In addition to the advancements in optoelectronic light sources, and especially quantum and interband cascade lasers (QCLs, ICLs) largely driving the increasing interest in the MIR regime, also thermal emitters and light emitting diodes (LEDs) offer opportunities to alternatively fill current gaps in spectral coverage specifically with analytical applications and chem/bio sensing/diagnostics in the focus. As MIR laser technology has been broadly covered in a variety of articles, the present review aims at summarizing recent developments in MIR non-laser light sources highlighting their analytical utility in the MIR wavelength range.
在中红外(MIR)光谱范围内,传感、安全与防御、节能和通信等领域已经成功展示了一系列应用。特别是,MIR 光源的快速和近期发展显著增加了人们对开发 MIR 光学系统、传感器和诊断技术的兴趣,特别是在化学/生物检测方案和分子分析应用场景方面。除了光电光源的进步,特别是量子和能带间级联激光器(QCLs、ICLs)极大地推动了人们对 MIR 区域的兴趣增加之外,热发射器和发光二极管(LEDs)也为替代当前的光谱覆盖范围提供了机会,特别是在分析应用和化学/生物传感/诊断方面。由于 MIR 激光技术已经在各种文章中广泛涵盖,本综述旨在总结 MIR 非激光光源的最新发展,强调它们在 MIR 波长范围内的分析应用。
