Paper Abstract

Throughout all this paper we are going to analyze one application of the optical beam deflection method (OBDM), the procedure for its development, as well as its ideal implementation to reach measurements of displacements that could be the most accurate and of the smaller scale possible, this condition is essential for the magnitude of the results to evaluate. We also give an application of the OBDM such as a fine particle densimeter principally in solids. This present work will analyze the laser beam deflection technique, the procedure to apply, as well as its ideal implementation in order to obtain measures of displacements that can sense to the most exact and the smaller possible scale, obtaining results from microns, micrometers and even, until nanometers. Our objectives that are considered in this investigation are two: the first one is to build a device based on this technique, make accurate measures on a very low scale, which could be reliable and in the order of scale of microns until nanometers. The second objective that we are searching is to obtain an alternative method for verify the values of density that some substances that are hard to get like titanium oxide.
