Abstract:
1. Apparatus comprising: a fluidic structure with a channel defined therein within which objects travel, the objects being capable of emanating light within a range of photon energies as the objects travel within the channel; and along the channel, a sensing component; the sensing component including: a set of cells of a photosensor array; and a transmission structure positioned so that emanating light from an object traveling within the channel can enter it; the transmission structure responding to emanating light that enters it by providing output light, the transmission structure being structured so that photon energies of the output light vary as a function of position; the sensing component being structured so that each of a subset of two or more cells in the set receives a respective part of the output light that is in a respective subrange of the range of photon energies and so that the subranges of at least two cells in the subset are different from each other; the transmission structure including at least one of:
