Multicolor photonic radiation detector

摘要

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.
