| 摘要 |
The present invention relates to an analyzer for determining the concentration of substances, such as chemicals, present in a fluid medium, such as gas, vapor or liquid, using holographic optics. The analyzer of the present invention is based on the infra red absorbance of the gas, vapor or liquid to be measured, where the optical functions of an infra red absorbance gas analyzer are performed by holographic functional representations of the required optical components. |
