Chapter and Conference Paper
Experimental Study on the Absolute Measurement of Flats
We present an absolute method of shift-rotation to calibrate the flatness of flats. Compared with the conventional three-flat test method, the method requires only two flat and no flips of the flats. And there...

Absolute measurement of flats with the method of shift-rotation
We present an absolute measurement of flats in a Fizeau interferometer with the method of shift-rotation, which only requires rotational measurements and shift measurement with a translation. Experiments have ...
