Abstract
We present a technique employing a speckle pattern correlation
method for detection of the slope of an object's surface. Controlled translation of
an object under investigation and numerical correlation of speckle patterns
recorded during its motion give information used to evaluate the tilt of the
object. The proposed optical setup uses a symmetrical arrangement of detection
planes in the image field and enables one to detect the tilt of an object's surface within
the interval
. Simulation analysis shows how to control the
measuring range. The presented theory, simulation analysis, and setup are verified
through an experiment by measurement of the slope of a surface of a cube made out
of steel.
