Abstract

Ilettigi birincil sinyallerle bir nesneyi görüntüleyen, birinci x-isini detektörü, ikinci x-isini detektörü arasina yerlestirilen isin paralellestiriciyi içeren görüntüleme sistemidir. Isin paralellestirici, detektörlerin biri içinde ölçülen, birincil bilesen ve saçilan sinyal bileseni içeren toplam sinyallerin ilgili dagilma bilesenlerini indirgemektedir. Detektörlerden biri toplam sinyalleri bulgulamakta; isin paralellestirici, kendisi ile odaksal olarak hizali ve birinci detektör içinden yol alan toplam sinyallerin birincil sinyallerini paralellestirmekte, diger detektör, paralellestirilmis, birincil sinyalleri bulgulamaktadir. Bulgulanan toplam sinyaller, saçilmis bilesenler, paralellestirilmis sinyaller ve tekabül eden, bulgulanan toplam sinyallere dayanilarak indirgenmektedir.
