Abstract
A tube is attached inside a container and forms an inlet aperture. A transparent bulb is sealed over the end of the tube. A fiber optic probe is inserted into the tube and bulb. The fiber optic probe is connected to a fiber optic transmitter and receiver, which sends a beam of light down the probe. The beam of light reflects off the contents of the container and the reflected light is received by the fiber optic probe. The fiber optic transmitter and receiver compares the light intensity of the reflected light with the light intensity of the light beam. Changes in this radio indicate there has been a change in the contents of the container.
Claims15
An optoelectronic chemical reaction detector comprising:
- a pressurized container having chemical reactants;
- a transparent member hermetically sealed within a wall of the container for allowing passage of light into and out of the container;
- and
- an optic transmitter and receiver positioned proximate the transparent window and in optical communication with said chemical reactants, for transmitting a light beam to said chemical reactants and comparing the intensity of said light beam as originally transmitted with the intensity of said light beam after being reflected off of said chemical reactants.
An optoelectronic chemical reaction detector comprising:
- a pressurized container having a supply of chemical reactants;
- a tube extending through and into the interior of the container;
- a transparent member hermetically sealed to the end of the tube and adjacent to said chemical reactants;
- a fiber optic probe positioned inside the tube and having a transmitting fiber optic cable and a receiving fiber optic cable, each of said cables terminating adjacent the transparent member such that each is in optical communication with said chemical reactants through the transparent member;
- and
- a fiber optic transmitter and receiver connected to said transmitting fiber optic cable and said receiving fiber optic cable for transmitting a light beam along said transmitting fiber optic cable to said reactants and comparing the intensity of said light beam as originally transmitted with the intensity of said light beam as received from said receiving fiber optic cable after being reflected off of said chemical reactants.
A method for detecting a chemical reaction comprising the steps of:
- filling a pressurized chamber with chemical reactants;
- hermetically sealing a transparent member over an aperture in said chamber;
- positioning a first end of a transmitting fiber optic cable adjacent said transparent member and connecting a second end to a fiber optic transmitter and receiver;
- positioning a first end of a receiving fiber optic cable adjacent said transparent member and connecting a second end to said fiber optic transmitter and receiver;
- operating said fiber optic transmitter and receiver to send a beam of light along said transmitting fiber optic cable and through said transparent member and hitting said chemical reactants to produce reflected light;
- receiving said reflected light in said receiving fiber optic cable and delivering said reflected light to said fiber optic transmitter and receiver;
- and
- operating said fiber optic transmitter and receiver to compare the intensity of the beam of light as originally transmitted with intensity of the reflected light in order to determine if said chemical reactants have fully reacted.
