Enhancement of surface inspection by Moiré interferometry using flexible reference gratings.
We have extended the use of shadow Moiré technique to be implemented in simple curved surfaces by using a flexible grating. Dynamic visual inspection of surface micro-damages is significantly favored by the use of well adapted pliable gratings compared to the use of flat reference gratings. The experimental set-up consists of a plastic foil with a printed Ronchi grating stretched between three ...
متن کاملInterferometry for Online/In-Process Surface Inspection
Interferometers are normally operated in environment-controlled optical laboratories because vibrations will induce errors in measurement results. In order to extend the application of interferometry to shop floor inspection, two methods are adapted: one method is to introduce a reference interferometer and vibration compensation system to the main interferometer, to compensate for the environm...
متن کاملMoiré interferometry with white light.
While high-sensitivity moiré interferometry requires monochromatic light, an auxiliary compensator grating removes the requirement. Experimental verification utilized white light for moiré interference of sensitivity 0.833 microm/fringe. Configurations readily amenable to compensation include moiré fringe multiplication by even factors and the minimum-deviation arrangement. Chromatic compensati...
متن کاملTime-averaged patterns produced by stochastic moiré gratings
A simple computational algorithm is proposed for visualization of time-averaged moiré fringes. Timeaveraging numerical techniques can be exploited for the construction of a cryptographic hash function. It appears that visualization of values of that hash function at continuously increasing amplitude of harmonic oscillation can produce interesting optical patterns. Chaotic and visually intriguin...
متن کاملHeterodyne moiré surface profilometry.
In this study, a novel moiré fringe analysis technique is proposed for measuring the surface profile of an object. After applying a relative displacement between two gratings at a constant velocity, every pixel of CMOS camera can capture a heterodyne moiré signal. The precise phase distribution of the moiré fringes can be extracted using a one-dimensional fast Fourier transform (FFT) analysis o...
