Abstract
Risley Prisms are traditionally used to point narrow band imaging sources (such as lasers) via the rotation of two or more prisms relative to each other. A less common application is the ability to steer broader spectral band imagery in each of the SWIR, MWIR, and LWIR spectral bands by utilizing achromatized prism pairs enabling high speed step stare and/or two-dimensional scanning at large pointing angles without the use of a gimbal or scanning mirror. In this paper, the recent advancements, capabilities, and limitations will be discussed.
