PROBLEM TO BE SOLVED: To provide a solid-state imaging apparatus which utilizes infrared light from a medium-infrared region to a far-infrared region, improves a material discrimination performance and is capable of acquiring image information.SOLUTION: A solid-state imaging apparatus 1 comprises a light source 2 that irradiates a subject with infrared light, an image forming optical member 3, an infrared detection element 4 and a wavelength transmission filter array 5. In the infrared detection element, a plurality of pixels having sensitivities in a wavelength band to be detected are arranged in a two-dimensional array shape. The wavelength transmission filter array 5 is disposed between the image forming optical member 3 and the infrared detection element 4 and proximately to the infrared detection element 4, and a plurality of wavelength transmission filters 5 of which the wavelength bands to be transmitted are different in a wavelength band to be transmitted are arrayed on a plane.SELECTED DRAWING: Figure 1 |
