Remote Sensing Systems: the Human Eye Spectral Resolution: µ m Spatial Resolution: ~ m Radiometric Resolution: ~16-32 shades B/W or ~100 colors

Human Eye Retina Rods & Cones: our visible detectors 120 Million rods, 5 Million cones, & 1 million optic axons Cones-- color sensitive, form sharp images, require many photons Rods are intensity, but not color sensitive, & form blurred images Birds-- big eyes, more cones, “faster” eye muscles, more support, and best vision (8x better than ours) Nocturnal animals have big eyes & more rods/fewer cones

Our vision is optimized for receiving the most abundant spectral radiance our star emits. Evolution?

Human Eye and Retina

Eye Cross-section, Front, & Back

Human Vision Visible photons --> electrical charge Nerve impulses are electro-chemical Information transmitted to brain for processing

Human Vision -- could be better to processor Not optimum design--lots of nerve cells in optical pathway (give us a few more million years without a major extinction event…)

The Octopus has a comparable eye to ours-- an example of parallel evolution

Insect visual simulation at 2-3 m Albert Einstein Image projected onto compound eye Insect views AE You be the judge
