Fundamentals of Diffraction and Image Formation
Abstract:
After a brief reminder of 2-dimensional Fourier formalism, we will address the diffraction theory and the limitation it imposes. Then, some approximations will be made in order to simplify the calculations into simple mathematical operations. The explicit calculation will be done in detail to demonstrate one of the most remarkable and useful properties of a converging lens, namely its ability to perform 2-dimensionnal Fourier-transforms. Finally, a general study of image formation systems we will addressed by introducing the notion of optical transfer function in the case of spatially coherent and incoherent illumination.
