AbrégéEmbodiments disclosed herein address these and other issues by providing for an optical tag that uses an optical assembly with beam splitters to allow for simultaneous detection and retro-modulation, as well as the use of a camera to facilitate alignment of the optical tag with a laser interrogator. Additional components may be used to allow for a large aperture to be used, to help maximize light received by the optical tag and minimize diffraction of retro-modulated light, which can significantly increase distances at which the optical tag can operate. Moreover, a beam splitter may further be used to balance the light directed toward an optical sensor and a retro-modulator, to help achieve optimal results.
