Abstract
A method of illuminating and extracting scattered and transmitted light from a liquid within a sealed glass bottle, the method comprising initiating transmission of an incident light beam from a light source to the sealed bottle, directing the incident light beam to totally internally refract within a wall of the sealed bottle and thereby cause an evanescent wave within the liquid to generate scattered or absorbed light, receiving the scattered or absorbed light from the liquid contained in the sealed bottle, and processing one or more signals representative of the scattered or absorbed light, the signals indicative of one or more molecules indicative of a characteristic being present in the liquid contained in the sealed bottle.
Claims14
A method of illuminating and extracting scattered and transmitted light from a liquid within a sealed bottle, the method comprising:
- initiating transmission of an incident light beam from one or more light sources to the sealed bottle;
- directing the incident light beam into the liquid within the sealed bottle at a first position to cause the liquid to generate scattered light and a wall of the sealed bottle to generate scattered light;
- receiving, from a second position that is different than the first position, the scattered light from the liquid and the scattered light from the wall;
- separating the scattered light from the liquid and the scattered light from the wall into one or more first signals representative of a first space-resolved image of the liquid and one or more second signals representative of a second space-resolved image of the wall, the first and second images comprising spatially separated images;
- and
- processing the one or more first signals to detect one or more molecules indicative of a characteristic being present in the liquid contained in the sealed bottle.
A system for illuminating and extracting scattered and transmitted light from a liquid within a sealed bottle, the system comprising:
- a light source configured to allow initiation of transmission of an incident light beam to the sealed bottle;
- one or more optical elements configured to:
- direct the incident light beam into the liquid within the sealed bottle at a first position to cause the liquid to generate scattered light and a wall of the sealed bottle to generate scattered light,
- receive, from a second position that is different than the first position, the scattered light from the liquid and the scattered light from the wall, and
- separate the scattered light from the liquid and the scattered light from the wall into one or more first signals representative of a first space-resolved image of the liquid and one or more second signals representative of a second space-resolved image of the wall, the first and second images comprising spatially separated images;
- and
- a processor configured to process the one or more first signals to detect one or more molecules indicative of a characteristic being present in the liquid contained in the sealed bottle.
