Abstract
An encoded microparticle including an optical substrate comprising a material that permits light to propagate therethrough. The optical substrate has an elongated body that extends in a direction along a central axis. The optical substrate includes an outer region that extends about the central axis. The encoded microparticle also includes an optically detectable code that is disposed within the optical substrate and extends along the central axis. The outer region surrounds the optically detectable code about the central axis. The optically detectable code is readable when the light propagates through the outer region and is at least one of reflected or filtered by the optically detectable code. Said at least one of reflected or filtered light propagates through the outer region to be detected for reading the optically detectable code.
