Primarily, …
WebAn incoherent spotlight-mode SAIL was proposed, and detailed mathematically. To validate the concepts, laboratory experiments were conducted. The spatially and temporally … 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: …
