Aside from popular limits that each one imaging systems share, e. g., spatial resolution and contrast ratio, picture intensifier systems are most recognized for vignetting and distortion artifacts. Vignetting, as explained in Fig. seven.15, describes a drop in brightness that occurs on the outer areas of the display screen. It truly is attributable to light scattering that deflects gentle photons inside the output phosphor in the outer Element of the phosphor to The within. Nevertheless, no scattering takes place from fully outdoors the material into the outer areas of the phosphor, yielding an elevated brightness on the central locations.
