Building Optics That Can See Around Objects

Applied Science · Demo · 14 min · 2020 · YouTube title: Hypercentric optics: A camera lens that can see behind objects
Why it's here

Commenters cite it as the clearest demonstration of hypercentric lenses and of looking around objects with optics.

What it covers

Applied Science shows how telecentric and hypercentric optics differ from normal lenses, producing no or negative perspective. The video builds a telecentric system from a Fresnel lens and demonstrates a lens that can see around objects.
