Incoherent imaging
http://web.mit.edu/2.710/Fall06/2.710-wk11-a-sl.pdf WebIncoherent light, such as sunlight from a cloudy sky, and coherent light from a laser, are each limiting theoretical constructs. Even though using these conditional limits simplifies the process of writing equations that describe the image formation process in the microscope, neither coherence extreme can actually be realized in practice.

WebThe transfer function itself is merely the scaled version of pupil function for coherent light, and pupil autocorrelation for incoherent light. In effect, the system impulse response acts as a smoothing spatial filter, softening edges, reducing amplitude, and suppressing high frequency distributions. In the frequency domain, system's transfer ...
