Paper Abstract
A method of calibrating profilometer transmission characteristics with a heterodyne interferometer is described. This method has the advantages of high precision, setting no strict demands on the environment and being efficient. The work range of the calibrating system is from 0.15 micrometers to 40 micrometers for Ra. The uncertainty of the calibrating is +/- 1%, and the frequency is between 1 Hz and 180 Hz.
