WebThe method is applied to generate edge-enhanced images in both CAI as well as Fresnel incoherent correlation holography methods. Coded aperture imaging (CAI) methods offer multidimensional and multispectral imaging capabilities with minimal resources than what is needed in a lens-based direct imager. WebNext, we are going to look at 3 cases, a fully incoherent image of this source, a fully incoherent image, a fully coherent image and a partial coherent image. A fully coherent image: The resulting image shows the general blurring expected (as a result of diffraction) but no coherent interference. A fully coherent image
