Abstract

Spectrally Controlled Interferometry measures surface form and radius in one measurement. Earlier results demonstrated ~30 PPM uncertainty, which rivals the standard DMI radius measurement, from a simple proof-of-concept test without careful compensation for the ambient environment. Results showing improved uncertainty through better calibration including environmental compensation are presented.
