Multimodal tuned dynamic absorber for split Stirling linear cryocooler

Low size, weight, power and price split Stirling linear cryocooler usually comprises electro-dynamically driven compressor and pneumatically driven expander which are side-by-side fixedly mounted upon the common frame and interconnected by the configurable transfer line. Vibration export produced by such a cryocooler comprises of a pair of tonal forces, the frequency of which essentially equals fixed driving frequency. In vibration sensitive applications, this may result in excessive angular line of sight jitter and translational defocusing affecting the image quality. The authors present Multimodal Tuned Dynamic Absorber, having one translational and two tilting modes essentially tuned to the driving frequency. Dynamic...

    - Perimeter SecuritySCD’s high-end, XBn (HOT) and InSb detectors were specially developed for applications where 24/7 operation is a must. These cooled detectors are successfully integrated into Perimeter Security systems thanks to their superior performance, high reliability and endurance to harsh environmental conditions.
    - Long Range SurveillanceSCD’s detectors are used in long range surveillance thermal cameras. Thanks to the detectors’ high resolution imaging, these cameras are successfully used in any environment from heavy fog to complete darkness and for 24/7 situational awareness and long-range recognition and identification of targets.
    - Public Safety & TransportationThermal cameras are one of the most suitable solutions for making public transportation safer. Public transportation passengers rely on trains, metros or trams to bring them safely and timely to their destination and accidents caused by fire or objects lying on secured areas (areas which should be free of objects) can lead to delays as well as severe personal damage. Thermal imaging cameras can detect many of these incidents in time and therefore help public transportation operators take the appropriate measures in advance. SCD’s wide portfolio of cooled and uncooled detectors, cover the entire infrared spectrum and are consistently integrated into these cameras in order to improve the everyday public safety of transportation.

    - Missile SeekersSCD’s Pelican-D JT is an MWIR detector specially designed for missile applications. The FPA is InSb based, having a digital Readout Integrated Circuit (ROIC) in a format of 640 x 512 with 15μm pitch. Pelican-D JT has a unique structure of Dewar which enables very fast cool down time and hence quick mission readiness using a Joule-Thomson (JT) cooler. Due to the low heat load on the focal plane, the detector achieves long mission duration, a basic requirement for missile applications.
