摘要	In order to obtain enough information about the target and make full use of medium- and long-wave infrared spectral data, this article describes a harmonic diffractive/refractive (HDE) optical imaging system. Taking advantage of its special dispersion capability, the application of HDE in the infrared dual-band provides hundreds of spectral images in infrared band, medium-wave infrared band of 3. 7-4. 8 mu m and long-wave infrared band of 8-12 mu m. The design results show that: at 18 lines/mm, the optical modulation transfer function is greater than 0. 55 in medium-wave infrared band; at 13 lines/mm the optical modulation transfer is greater than 0.5 in long-wave infrared band; in the circle of 30 mu m radius, the encircled energy is greater than 85% in medium-wave infrared band; in the circle of 38 mu m radius, the encircle energy is great than 80% in long-wave infrared band; the spectral resolution is 0. 039 mu m at 4. 25 mu m and 0. 072 mu m at 8. 5 mu m respectively. So the optical modulation transfer function in infrared dual-band is close to the diffraction limit, and the encircled energy meets the energy requirement of one pixel of existing domestic detectors.
