Optical design method for minimization of ghost stray light intensity

WebThis is a simplified diagram replicating a common artefact seen on OPG. As the x-ray source and detector rotate around the patient dense objects (such as an earring) at the edge of the case, outside the focal trough - can cause 'ghost images'. These are seen at the contralateral aspect of the image and are distorted. WebGhost imaging captures 2D images with a point detector instead of an array sensor. It could therefore solve the challenge of building cameras in wave bands where sensors are difficult and expensive to produce and could open up more routine THz, near-infrared, lifetime, and hyperspectral imaging simply by using single-pixel detectors. Traditionally, ghost … those funny little people illinoisWebDimensions and, consequently, intensities of ghost images formed in an optical system can be estimated using an analytical algorithm. This algorithm enables construction of a merit function in optical design software, which returns a number proportional to the total intensity of ghost stray light. under armour holidays
