Although the clinical application of pulse oximetry has become widespread since the early 1980's, a convenient method for testing the operation and accuracy of commercial pulse oximeters does not yet exist. Our work has been directed toward the development of a calibrator that employs a liquid crystal light valve to simulate the optical signals measured by pulse oximeters. The feasibility of our calibration method has been demonstrated using a prototype device constructed in our laboratory.

尽管脉搏血氧饱和度的临床应用已经非常广泛 自20世纪80年代初以来，S就提出了一种方便的操作和测试方法 商业脉搏血氧仪的准确性尚不存在。我们的工作已经完成 致力于开发一种使用液体的校准器 用于模拟脉冲测量光信号的晶体光阀 血氧计。验证了该校准方法的可行性。 使用的是我们实验室建造的原型装置。
