Single time pixel imaging enabled by repurposing optoelectronic devices

Abstract

Abstract One-time readout temporal ghost imaging is attempted by utilizing optoelectronic devices that are not originally intended for signal photon detection purposes and as such slow by design. A visible light-emitting diode having a response time τ = 0.036 ms and a solar cell with τ = 3.1 ms are used to retrieve a rectangular pulse train, which is otherwise rounded with significant overlapping, in the image of a temporal mask simply by capturing data once at a selected single time pixel followed by division. Appropriate quality metrics and effective operation duration are discussed.
