| Abstract: | The problem of transmission of degrees of freedom of a general imaging system is discussed in this paper. The effective number of degrees of freedom of 1-D diffraction-limited system illuminated alternatively by coherent and incoherent light in the different cases of signal-to-noise ratio σ0/σn, is figured out, and contrasted with the number of picture-elements based on the traditional resolving power. |
