Title: Infrared image-pickup apparatus
Inventor: KUMADA NORIMASA
IPC: G01J5/48
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared image-pickup apparatus by which the images of infrared rays at a plurality of wavelengths can be picked up simultaneously without using a spectral diffraction means and by using a single optical detection element. SOLUTION: In an optical detection element 34, an intermediate infrared detector 35 which comprises a compound semiconductor light-receiving part on the front surface and a far- infrared detection part 36 which comprises an Si heterojunction light-receiving part on the rear surface are arranged on an si substrate, and respective pixels are patterned in geometrically identical position on the front and the rear. Infrared rays 1 which are condensed by an optical system 33 are first incident on the detection part 35 at the optical detection element 34. The detection part 35 is sensitive to intermediate infrared rays 10, and it is not sensitive to far-infrared rays 18. As a result, only the intermediate infrared rays 10 out of the incident infrared rays 1 are absorbed so as to be transducer into an electric signal.  The far-infrared rays 18 are transmitted through the detection part 35 so as to be incident on the detection part 36. The detection part 36 is sensitive to both the infrared rays 10 and the infrared rays 18, but only the infrared rays 18 are absorbed actually so as to be converted into an electric signal. Thereby, when a signal processing operation is executed to the infrared rays 10 and the infrared rats 18, the performance of an infrared imaging apparatus can be enhanced.
