Despite near infrared spectroscopy (NIRS) has been studied as an alternative measurement approach in various applications, NIRS measurement setup that used in most of studies is ambiguous. Thus, this study aims to review the measurement setup of different near infrared spectroscopic (NIRS) acquisition modes with respect to different types of instrumentation and samples, and to classify them systematically. The relationship among different reported acquisition modes was analysed. Different reported acquisition modes were classified based on the position of instruments in acquiring near infrared signals. A detailed analysis is provided to highlight the distinction of different NIRS acquisition modes. The challenges of existing measurement setups have been discussed. Interaction and diffuse reflection are the same because both measure diffuse signals that reflected from the inner parts of a sample. Finding shows that future NIRS investigation should address the concerns that related to the acquisition modes, unwanted signals, and measurement parameters.

尽管已将近红外光谱（NIRS）作为各种应用中的替代测量方法进行了研究，但大多数研究中使用的NIRS测量设置仍然模棱两可。因此，本研究旨在针对不同类型的仪器和样品，回顾不同近红外光谱（NIRS）采集模式的测量设置，并对它们进行系统地分类。分析了报告的不同采集方式之间的关系。根据仪器在采集近红外信号中的位置，对报告的不同采集模式进行了分类。提供详细分析以突出不同NIRS采集模式的区别。已经讨论了现有测量设置的挑战。相互作用和漫反射是相同的，因为它们都测量从样品内部反射的漫射信号。调查结果表明，未来的NIRS研究应解决与采集模式，有害信号和测量参数有关的问题。
