High-speed alternative phase-extraction method for imaging array-coupled binary moiré interferometry
Publikováno v:
Applied optics. 54(30)
An alternative phase-extraction methodology is presented for high-resolution moire analysis, in which the projected and imaged pattern is imaged by a charge-coupled device (CCD) array relatively spaced at three pixels per period. The profilometric me

Laser scatter has shown promise as a method to characterize damage microstructural variations as well as a method to characterize surfaces in optical translucent ceramics. Because large volumes of data need to be handled (and sorted) quickly, automat
