Abstract
Ghost imaging (GI) allows retrieval of the images of an uninterrogated object nonlocally based on cross correlation of photons. Central to GI is the integration of sparse detection events, i.e., bucket detection, even in the time domain. Here we report temporal single-pixel imaging of a non-integrating class as a viable GI variant that obviates the need for constant vigil. Mere division of the otherwise distorted waveforms by the known impulse response function of the detector makes the corrected waveforms readily available. This tempts us to use slow and as such less costly commercially available optoelectronic devices like light-emitting diodes and solar cells for imaging purposes on a one-time readout basis.
