Abstract

An excitation component or arrangement can provide excitation to a moving object so that information is encoded in time variation of light emanating from the object. For example, in each of a sequence of segments, it can provide a respective non-binary excitation spectrum, and the spectra can be different with a non-interference-like transition between them; because the object emanates light differently in response to the different spectra, photosensing results can be obtained that include encoded information about the object. The non-binary spectra could be different intermediate intensities, such as different gray levels or different intensities of one color or could be different colors. The excitation can be provided in a pattern with non-interference-like transitions between regions, and object motion can also be controlled.; In another approach, a trigger signal can cause a time-varying excitation in a region, with non-interference-like transitions between intervals of excitation, such as black/white, multiple colors, or gray levels.
