Abstract
A system and method for forming encoded microparticles is described. One embodiment includes an encoded microparticle, the microparticle comprising a plurality of segments aligned along an axis, wherein the plurality of segments define a code for the microparticle; and an outer cuboid encapsulating the plurality of segments, wherein the plurality of segments are detectable through the outer cuboid.
Claims20
An encoded microparticle, comprising:
- a first material comprising two or more code elements aligned along an axis;
- and
- a second material surrounding the first material such that the code elements are detectable through the second material;
- wherein the code elements form a code of the microparticle;
- wherein the microparticle has a consistent rectangular cross section shape along an entire length of the microparticle.
2 more elements
An encoded microparticle comprising:
- an elongated body comprising a plurality of alternating portions of a more transparent material and a less transparent material;
- wherein the portions of the less transparent material are adjacent to the portions of the more transparent material;
- wherein the portions of the more and less transparent materials represent a detectable code;
- wherein the portions of the more and less transparent materials are surrounded by a coating material;
- and
- wherein the microparticle has a consistent cross rectangular section shape along an entire length of the microparticle.
3 more elements
An encoded microparticle comprising:
- an elongated structure comprising a detectable spatial code, where the elongated structure has a substantially square cross section;
- and
- the elongated structure further comprises a material opaque to visible or near visible light and a material transmissive to the visible or near visible light, wherein the opaque material is enclosed within the transmissive material, and wherein the elongated structure has a consistent rectangular cross section shape along an entire length of the elongated structure.
