Abstract
A low cost, compact, opto-mechanical system for particle analysis is disclosed. In embodiments of this disclosure, the system includes: a holder configured to rigidly secure a container that contains a liquid sample; an actuator configured to repetitively rotate the holder N degrees in a first direction and M degrees in a second direction different from the first direction, wherein N and M are real numbers greater than zero; a radiation source configured to generate a beam of radiation, the radiation source being rigidly attached to the holder; and a detector configured to receive radiation that is at least one of scattered, reflected, diffracted, refracted, or radiated from one or more particles within the liquid sample in response to the beam of radiation being incident upon the one or more particles.
Claims19
A system for analyzing particles in a liquid sample, the system comprising:
- a holder configured to rigidly secure a container that contains a liquid sample;
- an actuator configured to repetitively rotate the holder N degrees in a first direction and M degrees in a second direction different from the first direction, wherein N and M are real numbers greater than zero;
- a radiation source configured to generate a beam of radiation, the radiation source being rigidly attached to the holder, the beam of radiation being directed through the container into the liquid sample;
- and
- a detector configured to receive radiation that is at least one of scattered, reflected, diffracted, refracted, or radiated from one or more particles within the liquid sample in response to the beam of radiation being incident upon the one or more particles.
A method of analyzing particles in a liquid sample, the method comprising:
- directing a beam of radiation from a radiation source into a container that contains a liquid sample;
- repetitively rotating the container N degrees in a first direction and M degrees in a second direction different from the first direction, wherein N and M are real numbers greater than zero;
- and
- detecting radiation that is at least one of scattered, reflected, diffracted, refracted, or radiated from one or more particles wherein the container is rigidly secured by a holder and the radiation source is rigidly attached to the holder within the liquid sample in response to the beam of radiation being incident upon the one or more particles.
