コールドミラーを用いた血中酸素飽和度の非接触計測

抄録

The purpose of this study is to propose a non-contact method of measuring arterial blood oxygen saturation and to evaluate the system. In this presentation, a camera was used to measure arterial blood oxygen saturation in a non-contact manner. In order to realize stable measurement, we investigated a method of using a cold mirror (a mirror that reflects visible light and transmits infrared light) to measure the light after spectroscopy with a camera. We believe that the use of a cold mirror for spectroscopy of infrared and visible light will increase the sensitivity of the sensor and reduce noise, and we report on the design, prototyping, and measurement experiments of the device.
