Claim:
1. An optical apparatus comprising: a first laser source configured to generate a first laser beam having a first wavelength in an infrared spectral range, the infrared spectral range including at least one of the short wavelength infrared (SWIR), mid wavelength infrared (MWIR), and long wavelength infrared (LWIR) spectral ranges; a holographic medium optically coupled to the laser source and having a transmittance range including the first wavelength; and a diffraction pattern formed in the holographic medium and which encodes an input image, the diffraction pattern configured to diffract the first laser beam responsive to being illuminated by the first laser beam so as to construct an image in one of the short wavelength infrared (SWIR), mid wavelength infrared (MWIR), and long wavelength infrared (LWIR) spectral ranges, the image being a reconstruction of the input image.
