Abstract
We present the design and experimental demonstration of an ultrathin four-reflection imager. The prototype imager achieves a focal length of in a track length of just , providing a field of view over 1.92 megapixels of a color image sensor with pixels. We also present the design and experimental results of pupil-phase encoding and postprocessing, which were applied to extend the depth of field and compensate a small amount of axial chromatic aberration present in the four-reflection imager prototype.
