Compliant Mechanisms Article

An excellent article on compliant mechanisms related to optical systems in the November 2013 edition of Nasa Tech Briefs.

This article discusses the ability to use AMCs (amorphous metal composites) for compliant mechanisms in place of typically used Aluminum and Titanium alloys.  Since these composites can be customized for material properties needed in an optomechanical design or other application, the design can be optimized for specific applications.  This can be critical for space based optical systems or aerospace systems.

SPIE currently has this article n the James Webb Space Telescope set to open access.  The JWST is an amazing work of engineering and optomechanical design.  This telescope has not yet launched into space, but when it does it will provide unparalleled infrared images.

The article goes into great detail behind the optomechanics of the telescope, and the image shown here is an amazing example of the kinematic design that goes into makiing an ultrastable lightweight mirror assembly.
