Paper Abstract

A novel design is presented for an electromagnetic device which provides linear translation of a focal plane detector array, for optical systems where a re-imaging plane is not available to use conventional angular beam steering mirrors. High bandwidth, high reliability without lubrication, and extremely low friction are achieved using two-axis magnetic motors which pivot a flexure mounted post. Near linear translation of the post-mounted detector array without defocus is provided by designing the optical system with a spherical focal plane matched to the radius of the post.
