Palomar History Photo of the Week - Resistance is Futile

Looking at this 1938 photo from the Caltech optical shop you might think that this optician was the inspiration for the Borg of the Star Trek universe.

In actuality he was performing a Foucault knife-edge test to measure the shape of one of the secondary mirrors for the 200-inch telescope.

By showing the full photo you can get a better sense of the mechanism that was being used.
