Abstract

Arrayed Wide-Angle Camera System (AWACS) is built on the segmented field corrector architecture that can break the limits of monolithic design in scaling to the ELTs and beyond. AWACS accomplishes desired field expansion via a suite of small cost-effective electro-opto-mechanical units over a telescope’s focal surface that compensates for telescope field aberrations and atmospheric dispersion, locally but simultaneously. These units are based on one common design where a pair of atmospheric dispersion compensation prisms and cylindrical lenses must be counter rotated to tune the level of corrections within a highly confined air space within each unit. This calls for a super tiny rotary mechanism and this paper details the results from prototyping ultra-sonic super compact rotary stages.
