A very simple method for the determination of a surface inclination is presented. The method is based on the direct analysis of the photographic record of two speckle-patterns produced by the diffusing surface, when illuminated by a single wavelength

When a point on a uniform background is observed through an astigmatic system (for instance, cylindrical lenses), the image will be a segment which is perpendicular to the cylinder. A line parallel to the cylinder would give an almost invisible image

Describes a simple method for nearly simultaneous measurement of a laser source spatial degree of coherence and coherence length. Modifying the Twymann-Green method, and after a 180 degrees rotation of one of the split beams, it is possible to produc

The absolute measurement of the intensity correlation of a speckle pattern was previously demonstrated by using a photographic real-time technique (1). In this paper we demonstrate its use for the measurement of surface roughness in the 1-30,μm rang
