Abstract

A star tracker includes imaging optics comprising a folding mirror, a lens, and a detector. The folding mirror bends light received from an optical axis through the lens that focuses the bent light onto the detector. The star tracker includes a steering mechanism that steers light from an adjustable field of view (FOV) to the optical axis of the imaging optics. The steering mechanism includes: (i) a first photonic crystal element comprising beam pointing spatially variant photonic crystals (SVPCs); (ii) a second photonic crystal element comprising beam pointing SVPCs that is positioned adjacent and axially aligned with the first photonic crystal element; and (iii) a housing that receives the first and second photonic crystal elements for independent rotation.
