Probabilities of detection of coherent optical signals in thermal background noise of a Lorentzian spectrum are calculated and compared for two cases: counting the number of photoelectrons within a fixed time <i>T</i> and measuring time intervals between photoelectrons within the same <i>T</i>. Although a comparison between the two methods is not always possible, it is shown that in some cases the counting method leads to better performance.
