Abstract
An electromagnetic wave detection apparatus 100 includes a wavelength separator 123 having a transmittance of electromagnetic waves in a first wavelength band larger than a transmittance of electromagnetic waves in a wavelength band other than the first wavelength band, a wavelength selector 124 having a transmittance of electromagnetic waves in a second wavelength band larger than a transmittance of electromagnetic waves in a wavelength band other than the second wavelength band, and a first detector 130 configured to detect electromagnetic waves progressing via the wavelength separator 123 and the wavelength selector 124. The first wavelength band and the second wavelength band partially overlap with each other.
