An approach to a wide-band frequency passive vibration attenuation is introduced in this paper. This aims to suppress noise and vibration of extended multimode objects like plates, panels and shells. The absorber is arranged in the form of a single-l

Operating infrared detectors at cryogenic temperatures is vital for attenuating intrinsic thermally-induced noise, thus enabling long working ranges, short integration times, high spatial and temperature resolutions along with other advantages. Unfor

Attenuation of tonal cryocooler induced vibration in infrared electro-optical payloads may be achieved by using of Tuned Dynamic Absorber (TDA) which is, generally speaking, a passive, weakly damped mass-spring system the resonant frequency of which

Cryogenically cooled infrared detectors are known to have better temperature resolution and shorter integration time as compared to the uncooled “competitors”. These advantages allow for longer detection distances, better spatial resolution and t

Modern infrared imagers often rely on split Stirling linear cryocoolers comprising compressor and expander, the relative position of which is governed by the optical design and packaging constraints. A force couple generated by imbalanced reciprocati

Tuned dynamic absorbers (TDA) find use, in particular, for attenuating tonal vibration export produced by the moving components of cryogenic cooler. For the best performance, the resonant frequency of TDA needs to be essentially equal the driving fre
