Dale,

You will need a laser and a rotation stage.

A grad student in a Astro research group here did that same measurement this summer. She borrowed my laser and used a rotation stage.

She shined a laser beam through the material and carefully measured the bend angle using a rotation stage.

Am I correct, Tappers? -- JZ

Do a little more of that work which you have confessed to be good,
Which you feel that society and your most Just Judge rightly demand of you.
Cultivate the tree which you have found to bear fruit in your soil.
If you have any experiments you would like to try, try them.
Now's your chance.

Henry David Thoreau, Journal entry, 1850.
