We present the design and experimental demonstration of an ultrathin four-reflection imager. The F / 1.15 prototype imager achieves a focal length of 18.6 mm in a track length of just 5.5 mm , providing a 17 ° field of view over 1.92 megapixels of a color image sensor with 3 μm 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.
