WebApr 23, 2024 · For incoherent sources, the phase difference takes all possible values. This is why the average of all such intensities is taken. And the average of $\cos\phi$ is $0$ which leads to both cases having the same net intensity.

However, when the light intensity is vigorous, the imaging performance of the network also deteriorates, as shown in Fig. 8. This is because the camera’s pixel values overflow under vigorous light intensity, and the information in …
