1. A system, comprising:
an excitation component configured to excite an emissive species such that the emissive species produces a detectable non-steady-state emission during an emission time period, wherein the emission time period is at least 10 nanoseconds and wherein the excitation component is configured to emit electromagnetic radiation having a wavelength of greater than 10 nm and less than 740 nm;
an image sensor comprising an array of pixels configured to detect at least a portion of the detectable non-steady-state emission, the image sensor comprising a rolling shutter; and
an electronic hardware component configured to produce a single image comprising a first portion corresponding to a first portion of the emission time period and a second portion corresponding to a second portion of the emission time period,
wherein the rolling shutter of the image sensor is configured, upon detection of the detectable non-steady-state emission, to sequentially read a first row or first column of pixels of the array of pixels and a second row or second column of pixels of the array of pixels,
wherein the first portion of the single image corresponds to a first portion of the detectable non-steady-state emission captured in the first row or first column of pixels, and
wherein the second portion of the single image corresponds to a second portion of the detectable non-steady-state emission captured in the second row or second column of pixels.
