Abstract

A new method of determining the surface shape of various objects including diffusely reflecting ones is proposed. The method relies on the use of polarization measurements. As a result of the application of this method, the total (resulting) object wave at each point of the reconstructed image turns out to be rotated by an angle whose value is proportional to the relief height at a given point and the direction of the angle of rotation determines the direction of the relief change. This method permits determining not only the value, but also the sign of the relief height; it also makes it possible to increase the resolution and accuracy of measurements.
