Abstract
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.
Claims17
An apparatus for determining the presence of light absorbing matter in a fluid medium, said apparatus comprising:
- means for collecting the fluid medium;
- a light source;
- a light detector;
- and
- a plurality of non-dispersive holographic optics positioned relative to said light source and said light detector, at least one of said plurality of holographic optics reflecting at least a portion of light from said light source through said collecting means to another one of said plurality of holographic optics, and one of said plurality of holographic optics reflecting at least a portion of the light to said light detector.
A method for determining the presence of light absorbing matter in a fluid medium, the method comprising the steps of:
- collecting the fluid medium;
- transmitting light through the fluid medium and to a plurality of non-dispersive holographic optics;
- reflecting at least a portion of the transmitted light from one of said plurality of holographic optics to another one of said plurality of holographic optics, and reflecting the transmitted light from one of said holographic optics to a light detector;
- and
- detecting the light transmitted from one of said plurality of holographic optics through the fluid medium to the light detector.
