Multichip imager with improved optical performance near the butt region

摘要: A compound imager consists of two or more individual chips, each with at least one line array sensors thereupon. Each chip has a glass support plate attached to the side from which light reaches arrays. The chips are butted together end-to-end make large arrays sensors. Because imperfections in cutting, surfaces define gap. Light entering region gap is either lost falls on an other than for it intended. This results vignetting and/or crosstalk near region. filled epoxy resin similar material which, when hardened, index referaction that plate.
