The work being presented takes a look at a method for efficiently simulating a short coherence length Lorentzian laser source and calculating the interference signal for many point scattering sources moving through space within a continuously changing coherence function. The detector’s time domain signal and its frequency domain spectrum will be calculated and evaluated. The results of the proposed simulation method are then compared to theoretical analyses found in literature.
