High-resolution moiré interferometry for quantitative low-cost, real-time surface profilometry

Not Accessible

Your library or personal account may give you access

Abstract

A two-dimensional optical profilometry system has been developed in which fringe projection and image processing methods allow for image acquisition and analysis at video frame rates with μm-scale precision in an inexpensive portable device. The device presented can be used to interrogate any uniformly reflective surface, imaging an area of approximately 10 square centimeters and providing a real-time digital display of the surface’s contours. The presented system has the ability to resolve surface features with a lateral resolution of <50μm and <15μm in height.
