Abstract
Objective speckle of sticking foil is a new approach to apply the objective speckle method into various materials for in-plane displacement measurememts. Specimen surface has been treated by sticking a thin layer of aluminium foil and scratching a random grating by relatively easy technique in order to form high reflectance and fine optical details. After double exposes by direct recording system without using lenses, the holographic film possesses a broad spatial spectrum range and displacement information. Full-field contour maps are obtained with clear lines of equal displacement, high sensitivity, and large adju-stable measurement range. It is available for practical engineering problems and for both plane and developable curved surfaces.
