Abstract
This disclosure discusses a Mueller Matrix Polarimetry system for real time identification of microorganisms in the field. The disclosed systems comprise a mechanical arrangement of optical elements that are configured to create a library of characteristic measurements for each organism. This library acts as a reference for comparison for signatures measured from unknown samples in the field. Elements described in the disclosure minimize moving parts as well as manual intervention, lending to use in portable, battery-operated devices.
Claims21
A portable system for detecting one or more microorganisms in a specimen, comprising:
- one or more light sources arranged to produce a light beam that is configured to interact with a receptacle positioned in the system;
- one or more filters, wherein the light beam is polarized by at least one of the one or more filters;
- one or more beam splitters;
- a plurality of sensors arranged along an arc, relative to a path of the light beam, and configured to detect scattered light at a plurality of angles relative to the receptacle;
- and
- a processor communicatively coupled to memory, the one or more light sources, and the plurality of sensors, the processor configured to execute instructions stored in the memory, the instructions comprising:
- receiving, from at least a subset of the plurality of sensors, detected scattered light signals from a sample that is positionable in the receptacle;
- identifying one or more optical signatures in the detected scatter signals from the sample,
- comparing the one or more identified optical signatures from the sample to a database of optical signatures, and
- outputting, based on the comparison, an indication of the one or more identified optical signatures from the sample.
