近红外光谱(NIR)如今被广泛应用于从监测工业制造过程到评估产品和材料的化学成分和质量的各种应用。然而，挑战仍然是减少这些光谱设备的尺寸和成本，同时保持它们的灵敏度和稳健性。光谱传感器的小型化对于将其应用从工业环境和分析实验室的专用站扩展到现场工作的非专业人员手中并最终扩展到消费者手中至关重要。目前的便携式近红外传感器系统的设计大多是受传统仪器的启发，这些仪器使用光栅或干涉仪。这些方法的缺点是，组装和包含易受冲击和机械振动影响的可移动部件非常复杂。
Near-infrared spectroscopy (NIR) is widely used today in applications ranging from monitoring industrial manufacturing processes to assessing the chemical composition and quality of products and materials. However, the challenge remains in reducing size and cost of these spectroscopic devices, while maintaining their sensitivity and robustness. The miniaturisation of spectral sensors is essential to expanding their application beyond dedicated stations in industrial settings and analytical labs, into the hands of non-specialists working on-site and eventually to consumers. The design of current portable NIR sensor systems is mostly inspired by conventional instruments that use gratings or interferometers. The drawback of these approaches is that they are complex to assemble and contain movable parts that are susceptible to shocks and mechanical vibrations.
