A design for a low-cost, heterodyne, frequency domain-diffuse optical spectroscopy system is presented and validated. The system uses a single wavelength of 785 nm and a single detector to illustrate the capability, but is built in a modular fashion to make it easily expandable to additional wavelengths and detectors. The design incorporates methods to allow software-based control over the system operating frequency, laser diode output amplitude, and detector gain. Validation methods include characterization of electrical designs as well as determination of the system stability and accuracy using tissue-mimicking optical phantoms. The system requires only basic equipment for its construction and can be built for under .
本文提出并验证了一种低成本、外差式、频域漫射光学光谱系统的设计。该系统使用785 nm的单一波长和单个探测器来说明其性能，但采用模块化设计，便于轻松扩展到其他波长和探测器。该设计采用了一些方法，允许通过软件控制来调节系统工作频率、激光二极管输出幅度和探测器增益。验证方法包括对电气设计进行特性描述，以及使用仿组织光学体模确定系统的稳定性和准确性。该系统构建仅需基本设备，成本可控制在……以下。 （原文最后“under”后面缺少具体金额等信息，翻译中保留原文格式）
