Histograms of speckle contrast estimates β1,2 and βV, obtained from simulated patterns each consisting of one million random numbers following a Bose–Einstein distribution (β0 = 1) and with means of (a) 〈I〉 = 10−4, (b) 〈I〉 = 3 × 10−4 and (c) 〈I〉 = 3 × 10−2. For (a) and (b) most of the estimates are at β = −1 and a minority at very high values. |
