Abstract: Infrared detection systems according to embodiments include an infrared detector, a storage, and a correction calculator. The infrared detector is configured to detect infrared light by absorbing and photoelectrically converting infrared light of a specific wavelength range. The infrared detector is capable of sweeping an absorption peak wavelength of an absorption spectrum of infrared light. The storage is configured to store a plurality of correction coefficients for correcting a detection value from the infrared detector in accordance with the absorption peak wavelength of the infrared detector with respect to a wavelength range of an atmospheric window. The correction calculator corrects the detection value from the infrared detector for each absorption peak wavelength using corresponding correction coefficients stored in the storage.
