碩士 === 國立中興大學 === 機械工程學系 === 86 === ABSTRACTFocused on the Phase-shifting technique, to measure the
profile of the wavefront of the object beam. Presenting the
"Phase-shifting auto calibration technique", by measuring the
voltage applying to the phase-shifter make the fringe patterns
change one cycle, we can get the calibration of the phase-
shifter in our optical system. By using the calibration to move
the PZT and get the phase-shifted patterns. After this, the PSI
algorithm can bring the phase-shifted fringe patterns to the
phase-map.However, we will meet the problem of " Mode p" if the
phase we want to measure is larger than p. The unwrapping
technique we use is "Cellular automata", and the "preunwrapping
filter" is also be used to deal with the high-noise in phase-
map. Finally, applying our system to some interferometers, and
bring the Zygo GPI-LC system auto to measure the phase of
wavefront.
