Page 23: ８－３ Detection Principle
As long as the kinds of composing gases are known, the mixing ratio(concentration) can be determined by measuring the refractive index. The optical interferometric sensor applied in the FI-800 displays “Interference fringes” on the image sensor. The interference fringes which shifts in proportion to refractive index is reflected onto the image sensor.
