Instead of binning the photon event in time, we propose doing the binning in the frequency domain. This allows us directly to sample the phasor field wavefront HF(xc,Ω) used for reconstructions. Ω stands for the frequency range for the phasor field wavefront. The equation for the Fourier Domain Histogram can be applied during measurements, which is a summation of complex phasors (or a separated real and imaginary part).
