Eye Resolution Lab
I would really like to use an inquiry based
laboratory for optics beginning with the discovery of the human eye. In
other words, do you know of a laboratory that would ask students to
measure the angular resolution of the human eye in arc minutes?
No, but this is something you can do yourself. Draw zebra stripes on a
piece of paper, and move it back away from the student. The sharp
contrast between black and white will slowly fade to just a more greyish
total. Its subjective of course, but anything with people is. If this
were done by a tv camera and a machine then you could have a graph. This
"modulation transfer function" is one characteristic of a lens system, one
often sees listings for how many "lines per mm" a camera lens can resolve.
