White Light Methods
1010103White Light MethodsAs already established in Chapter 8, spatial-phase sensitivity is an important figure of merit of QPI methods. Much of the spatial nonuniformities that have the effect of smoothing out the details in a quantitative-phase image are caused by speckle. This random interference phenomenon occurs due to coherent superposition of various fields both from the specimen itself and spurious reflections from interfaces in the optical setup, or unwanted scattering from dirt and imperfection associated with the optics (Ref. 1, for example, provides a detailed description of speckle). Using broa…
