Experimental demonstration of spectral domain computational ghost imaging by Piotr Ryczkowski, Caroline G. Amiot, John M. Dudley, Goëry Genty

“…Abstract We demonstrate computational spectral-domain ghost imaging by encoding complementary Fourier patterns directly onto the spectrum of a superluminescent laser diode using a programmable spectral filter. Spectral encoding before the object enables uniform spectral illumination across the beam profile, removing the need for light collection optics and yielding increased signal-to-noise ratio. …”
