TL;DR: Holographic scanners are suggested for imaging in the 8-13-Mm spectral region because of the narrow linewidth of received irradiance and their inherent advantages in refrigeration and reliability.
Abstract: Holographic scanners are suggested for imaging in the 8–13-μm spectral region. Advantages in refrigeration and reliability are pointed out. The narrow linewidth of received irradiance may limit passive systems to applications such as thermography, where multispectral imaging should be a useful diagnostic tool. Active systems, which do not suffer from this range limitation, offer inherent advantages with regard to resolution improvement via background discrimination and also with respect to countermeasures.
