abstract = "Design of Infra-red (IR) imaging systems requires solutions for overcoming thermal variations of IR lenses, in particular those fabricated out of Germanium. The known thermal dependence of the index of refraction of Germanium results in significant focal shift, which produces image blur. Known solutions to overcome the thermal fluctuations are reviewed. A solution based on an alloptical phase mask with no moving parts will be shown to provide improved imagery for broad band IR scenes in the presence of wide temperature variations. Phase mask design considerations and trade-offs are analyzed.",
