The design of a vibration isolation system must be restricted by the size and shape of the payload and the installation space, and the layout constrains are thus also discussed. ![]() Therefore, the stiffness and damping coefficient on each DOF could be obtained by limiting the vibration transmissibility, in accordance to actual requirements. When the system is totally decoupled, the vibration on each degree of freedom (DOF) can be analyzed independently. Additionally, the decoupling conditions of the system can be obtained. ![]() Therefore, the elimination of the rotational vibration caused by coupling becomes an important part of the design of the isolation system. Rotational vibration is attributed to two sources: transmitted from the mounting base and generated by modal coupling. In view of this, a design methodology is proposed for a passive vibration isolation system in an optical system with sensitive LOS. If you wish to access the documents related to the Invitation to Tender, you have to log in to the ESA Portal.The performance of an optical system with sensitive line-of-sight (LOS) is influenced by rotational vibration.

The isolator is also required to perform reliably in the space environment and therefore a preliminary space assessment will be part of the work.Procurement Policy: C(1) = Activity restricted to non-prime contractors (incl. This activity will start by performing a literature and market review, followed by design, prototype and manufacture of a laser isolator covering the visible to shortwave infrared range. In particular there is a need for lowloss isolators in the 600-1200nm range, which can also perform reliably at high laser power. Feedback can cause a source to become unstable with amplitude fluctuation, frequency shift, mode hopping, noise, and even damage. It is used to reduce or eliminate the effects of optical feedback and reflections of the laser's own energy back onto itself. The objective of this activity is to prototype, characterise and perform space assessment of an optical isolator for lasers in the visible range 600-1200nm.Description: An isolator is an essential component in many laser applications.
