| Title: | Analysis of the optical reconstruction of shearograms using oblique illumination | Authors: | Ng, T.W. | Issue Date: | Aug-1997 | Citation: | Ng, T.W. (1997-08). Analysis of the optical reconstruction of shearograms using oblique illumination. Review of Scientific Instruments 68 (8) : 3125-3129. ScholarBank@NUS Repository. | Abstract: | Oblique illumination has superseded the use of lenses in the optical reconstruction of shearograms. Nevertheless, the mechanism behind this operation has, hitherto, not been clearly elucidated. In this article, we describe this mechanism via the use of ray and wave optics principles. A comparative analysis of the performances using white-light and monochromatic illumination is also furnished. © 1997 American Institute of Physics. | Source Title: | Review of Scientific Instruments | URI: | http://scholarbank.nus.edu.sg/handle/10635/67746 | ISSN: | 00346748 |
