Optics: Large-Field-of-View Wide-Spectrum Artificial Reflecting Superposition Compound Eyes (Small 15/2014)

Artificial reflecting superposition compound eyes (RSCEs), inspired by the unique designs of their natural counterparts, possess superior optical features such as minimum chromatic aberration, wide‐angle field of view, high acuity to motion and enhanced sensitivity to light unmatched by state of‐the‐art refraction‐based lenses. On page 3050, H. Jiang and team realize a new type of lens that focuses based on reflection on an array of mirror boxes rather than refraction (i.e., through glass in conventional lenses).
