WebDec 10, 2001 · This book discusses the characteristics of a diffraction image of an incoherent or a coherent object formed by an aberrated imaging system. Numerical results in aberrated imaging have been emphasized to maximize the practical use of the material. This second printing includes a number of updates and corrections to the first printing. WebCoherence In wave optics, we make a distinction between coherent and incoherent sources of light. Any real source of light is not exactly monochromatic (single color), but has a range or band of frequencies, Δ f. An incoherent source of light lacks a specific direction and has a relatively large Δ f. By contrast, a coherent source has a specific direction with a much …

"WebMar 1, 2024 · For incoherent imaging system, the incoherent transform function, also called optical transform function (OTF) is used. OTF is defined as the inverse Fourier transform of incoherent PSF. The OTFs of the synthetic aperture for 4 apertures-vision systems and one aperture are given in Fig. 3 a and b, respectively.

WebCoded aperture imaging (CAI) methods offer multidimensional and multispectral imaging capabilities with minimal resources than what is needed in a lens-based direct imager. In the CAI method, the light diffracted from an object is modulated by a coded mask, and the resulting intensity distribution is recorded. Most of the CAI techniques involve two steps: … WebApr 3, 2024 · Pattern recognition techniques form the heart of most, if not all, incoherent linear shift-invariant systems. When an object is recorded using a camera, the object information is sampled by the point spread function (PSF) of the system, replacing every object point with the PSF in the sensor. The PSF is a sharp Kronecker Delta-like function ...
