WebMar 1, 2024 · A common way of reducing the spatial coherence of a laser is to generate many speckle patterns with a time-varying scattering system and then sum the intensities. Even though each speckle pattern has a contrast of unity, an incoherent sum of N uncorrelated speckle patterns reduces the speckle contrast by a factor of N 1/2.

We see that while the quasi-coherent approximation is qualitatively similar to the incoherent summation, there is clear quantitative differences between the two models. WebSep 16, 2024 · An object is often illuminated by a spatially incoherent light source and then imaged. The field reflected or transmitted by the object is then partially coherent. We have shown in Chapter 5 that the degree of mutual coherence in the object increases when the distance between the source and the object is increased.

Webincoherent summation is to multiply the EXSIM FAS by N. The results of doing so are shown in Figure 2, where it is clear that the underestimation of the FAS by EXSIM is equal to 1 N, thus strongly suggesting that the underestimation is due to incoherent summation.
