Two-dimensional weak radiation detector with a detection means based on orthogonal modulation

A two-dimensional weak radiation detector, comprising:

• a photoelectric conversion part which emits electrons by incidence of photons;
• an amplification module which is placed to face the photoelectric conversion part, and is provided with a number of electron amplification parts that amplify the electrons emitted by the photoelectric conversion part;
• a detection module which is provided to correspond to each of said electron amplification parts constituting the amplification module, and is provided with a number of electron detection parts on which electrons from the electron amplification parts are incident;
• an operation control part which operates each of said electron detection parts constituting the detection module based on an orthogonal modulation pattern;
• a data read part which combines signals detected by a number of electron detection parts operated by said operation control part based on an orthogonal modulation pattern in time sequence and outputs the combined signals;
• a light incidence position calculation part which obtains positions of said photons incident on said photoelectric conversion part, based on a control signal of the operation control part and an output signal of each of said electron detection parts;
• and
• a wavelength calculation part which obtains energy of said photons based on a magnitude of the output signal of each of said electron detection parts, and converts the magnitude into a color signal.
