Paper Abstract

The advantages of the common Rotary Stirling cycle coolers over the Split Stirling Linear are the overall size, light weight, low cooler input power and high efficiency. The main disadvantage has always been self induced vibration. Self induced vibration is a major consideration in the design of stabilized IR imaging systems/(GIMBALS) due to the effect it has on image quality i.e. Jitter. The "irregular shape" of the Rotary cooling engine attached to the payload and optics is also a problem in terms of the limits it has on optical system size. To address these issues, FLIR Systems Inc in Boston MA, developed a new rotary Stirling cycle cooling engine known as the FLIR Submicro Cooler. The Submicro is now in production and has been applied in a few products especially in FLIR"S smallest GIMBAL which measures 7.0 inch in spherical diameter. In this paper we discuss the improvements made in terms of IDCA implementation in stabilized imaging systems.
