ABSTRACT:
A multicolor radiation detector capable of detecting at least two incident radiations with two distinct wave lengths .lambda.i1 and .lambda.s1 where wave length .lambda.s1 is greater than wave length .lambda.i1. The multicolor radiation detector includes two detection components. The first detection component is configured to detect at least the radiation with wave length .lambda.i1 and to be transparent to at least to the radiation of wave length .lambda.s1. The first detection component includes a matrix of detection pixels of n1 rows and m1 columns and a matrix of reading pixels of n1 rows and m1 columns wherein the reading pixels are transparent to the radiation with wave length .lambda.s1 in at least one portion of each pixel. The second detection component is configured to detect at least the radiation with wave length .lambda.s1. The second detection component includes a matrix of detection pixels of n2 rows and m2 columns and a matrix of reading pixels of n2 rows and m2 columns. The first detection component is configured to face incident radiation such that the first detection component receives the incident radiation of wave length .lambda.i1 before the second detection component receives the radiation of wave length .lambda.s1 and n1, m1, n2 and m2 are whole numbers equal to or greater than one.
