متن کاملMeasurement of nonlinear optical coefficients by phase-matched harmonic generation
A wide range of nonlinear optical coefficients and various systems of notation have been used to describe optical second-harmonic generation (5MG). To avoid possible confusion, the techniques of optical nonlinear coefficient measurement and the elementary theory of SHG are briefly reviewed. Absolute and relative nonlinear coefficient measurements by phase-matched SHG are described. The followin...
متن کاملSimulation of Adaptive Sampling in Profile Measurement for Structured Surfaces
Adaptive sampling is a novel sampling design that can redirect sampling effort during a survey in response to the observed values. Its application on surface texture measurement is new, such as working with stylus profilometers. As a start, this paper focuses on a classical one-dimensional adaptive sampling in surface texture measurement for structured surfaces. The sampling simulations show th...
متن کاملDeformation of Dynamic Surfaces
Based on dynamic fourth order partial differential equations, we present an iterative finite difference algorithm. With C++ language and OpenGL graphics library, we implement the finite difference algorithm into a user interface and develop shape control parameters, density, damping coefficient, boundary tangents and external forces into user handles for dynamic manipulation of surface deformat...
متن کاملOptical Inner Profile Measurement for Pipes and Tubes
This paper summarizes a principle for measurement of inner diameter or profile of pipes and tubes using optical method. Based on this principle, compact probes have been developed for industrial applications such as car industry, heavy industry and civil engineering. In addition to large probes for pipes, tubes and tank-like objects with diameter larger than 1meter, such small size probes as 5m...
